Thanks man! I try to talk through and explain the entire process. It's kind of hard to turn wrenches and hold a camera at the same time. 😆 Was there something you weren't able to follow? That said, this video is quite a few years old. We bought a house in 2020 with a garage, so no more wrenching in the parking lot and I can make better videos. 😁

To clean the throttle body you should take it off and clean the other side which is the side that gets dirty. The side you showed in the video doesn’t usually get very dirty. It’s the other side that gets gunked up with carbon and causes some idling issues.

The oil fumes make that "s" shaped pcv hose get soft and rotten over time, good to get one off Amazon and have on hand if that hose needs replaced, most parts stores don't have it, but can order one for twice the price, then wait a day or two for it. Nothing else will do. Not a bad job, overall.

So, look it up on KZbin your video came up 🙂 !!! Your approach, filming and step by step clarity is top shelf🏆and very thorough 💯. I liked all your suggestions to clean the map sensor and throttle- body. Replacing the springs that connect to the spark plugs ...great idea (how big and where'd you buy them?). Thats probably better than using dielectric gel. Now I know exactly what to do and what to expect. You deserve the 👑 and 🎯❤ for brightening up 🌞 my day with your high octane ⛽⚡ explanation to accomplish this job🔥 precisely... So, thanks again🙏. I want to do a video soon and I hope I can do one as well as you have. It's truly been a pleasure🏝🛻 !!!

Hi! Good question. It's been years since I had to do this. If I recall correctly, the biggest problem I had was defective sensors. Had to replace a couple but afterwards had no further issues. Have you tried the procedure listed below (and in the links)? 1. Turn ON the ignition, with the engine OFF. 2. Apply the parking brake. 3. Turn the exterior lamp switch from OFF to parking lamps 4 times within 4 seconds. A double horn chirp will sound and the low tire pressure indicator will begin to flash indicating the learn mode has been enabled.

I’ve had 3 Colorado crew cabs with a 3.5. (2005). I’ve had issues with the drivers side window. Could it be a grounding issue? All 3 did the same thing!
@CompTechMike
@CompTechMike 11 ай бұрын
Hi Richard! Thanks for checking out my Colorado videos. When you say "I've had issues with the drivers side window", what issue are you referring to, specifically? That said, yes, grounding issues are very common in these Colorado's. There are two grounding blocks under the hood (one located on the inside fender roughly near the battery, and the other on the opposite side by the air filter box) that frequently cause trouble. One suggestion is to disassemble them and clean them, scuff a bit of paint off where they bolt (so they can make better contact), or you could replace them with a standard bolt and ring terminals. There are also ground points along the frame that can become loose or corroded over time and are worth inspecting. Besides that, I know those switches in the door can go bad. I've had to replace a few of them myself. Look for replacement switches from a reputable seller like RockAuto.com; I've had "hit-or-miss" luck buying cheap ones off sites like eBay & Amazon. Dust, water, and other stuff coming in through the window, as well as frequent use, are culprits for these switches wearing out. You can start by checking and wiggling connections or using electrical contact cleaner spray. A third point to check is the rubber passage between the door and body of the vehicle. All the wires run through that narrow path and can become pinched or worn over time. Of course there are also mechanical points of failure such as the motor, regulator, fuse, or relay. Obviously without seeing the vehicle it's tough to say for sure, but hopefully this list of things to check will get you started. I'd also recommend looking on forums like ColoradoFans.com, 355nation.net, and the Facebook group "Chevy Colorado & Canyon (First Gen) Fan And Owner Page". Hope this helps, good luck!

@CompTechMike
@CompTechMike 2 жыл бұрын
Hi! Thanks for the comment. Glad the video is helpful. 🙂 The issue you are describing is called "Passlock". Passlock is a rudimentary anti-theft system installed in all 1st generation Colorado's, Canyons, and their variants (Hummer, Isuzu). It is a problematic system that has been discussed to death in the forums and will eventually fail on 100% of 1st generation trucks. The way it works is, it uses a sensor inside the ignition cylinder to detect theft attempts. When it engages it "thinks the vehicle is being stolen" and it disables the fuel pump for 10 minutes, preventing the truck from starting. You'll get light on your dashboard with a lock symbol and a "crank no-start" situation - the engine will crank but won't be able to start because the fuel pump has been disabled. Note - if your truck does not crank at all it's not Passlock. If it doesn't crank at all suggest checking battery, cables, grounds, fuses, ignition cylinder, or starter - in that order. When Passlock fails (and it will fail, eventually) there are three common solutions. You can either replace the module (but eventually it will fail again), you can cut a wire under the dash, or you can have it disabled with a tune ("VATS Delete"). Most tune shops that work on our trucks are able to do this. If you do not have a local tuner you can remove your PCM and send it off to a company like "PCM of NC". That's what I did way back in 2014 when mine first started acting up. No problems starting since, and I also had them do things like adjust for tire size and remove the speed limiter. Hope this information helps. Here's a few additional links: To learn more about Passlock: www.locksmithledger.com/keys-tools/article/10238356/general-motors-vehicles-equipped-with-passlock To learn about how to "cut the wire": www.coloradofans.com/threads/how-to-permanently-disable-the-passlock-ii-system.142238/ To send your PCM off for VATS delete I recommend this company: www.pcmofnc.com/ Side note: Some vehicles specifically manufactured in Canada may have PassKey instead of Passlock. This was only for a year or two and only on Canada-manufactured vehicles.

Alright Mike so I’m wondering if you can possible help me. Before changing my spark plugs my truck did not have a check engine light. I replaced my spark plugs at 99,500 miles. I used AC Delco iridium plugs properly gapped to spec. Soon after driving with the new plugs the CEL came on. Now when I was changing the plugs cylinder 2 had oil all in the spark plug well. So that lead to me getting the valve cover gasket, tube seals, and intake manifold gasket replaced. Today I just replaced the upstream and downstream o2 sensors. I recently just cleaned the throttle body, map sensor, and MAF sensor. My truck idles at 600 RPM. The code that was scanned at Autozone was P0420 something relating to the catalytic converter. I have had all this work done and the CEL is still on. It’s driving me insane. Please if you could try and help me I would appreciate it. 2008 Colorado 3.7L 4x4.
@CompTechMike
@CompTechMike Жыл бұрын
Hi Andrew! P0420 in a Chevy Colorado often indicates an issue with the O2 sensors or catalytic converter. It sounds like you're doing all the right troubleshooting steps, but I'd suggest the following: (1) Get your own code scanner. Clear the code and verify if it still comes back again. If so, after how long before it comes back on? (2) Get a scanner that's able to read real time data. Verify that it's showing data coming off the O2 sensors. I'm not suggesting you be able to understand the data (although this wouldn't hurt), but just be able to confirm that the truck's computer is showing data coming from the sensors. It could be a loose or damaged wire or connector causing the truck to not "see" the sensor, if that makes sense? (3) Double check your part numbers. I usually recommend a site like RockAuto. There's always the slight possibility that Autozone sold you the wrong parts, or that you received defective parts (this goes back to being able to see if there's data coming into the computer from the sensors). (4) Inspect for exhaust leaks. It's pretty common for the exhaust manifold on the Colorado to develop cracks over time. Listen and feel around the exhaust for any indications of a leak. Follow the pipes back to where they connect to the two catalytic converters for any leaks or breaks. Be careful not to touch - **hot!** (5) Any bad smells coming from the truck? A failed catalytic converter is usually described as smelling like "rotten eggs". 99k miles is pretty low, but we are talking about a 15-year-old truck, after all. So I'd start with those things. Verify that if you clear the code, it comes back. Verify the replacement sensors are sending data. Check for bad wiring, possibly a bad or defective part, and check for exhaust leaks. You can also check out this article for suggestions: www.700r4transmissionhq.com/p0420-chevy-colorado/ If you're still having trouble I recommend forums like 355nation.net and coloradofans.com, and also the Facebook group "Chevy Colorado & Canyon (First Gen) Fan And Owner Page": facebook.com/groups/1191961547485485 Good luck, if you find the solution come back and let us know.

@@CompTechMike first of all thanks for the quick reply. I got this truck actually one year ago on this day. The first thing I did was replace the exhaust manifold and gasket. Not the cheap one that comes with it but one from GM dealer that I had to special order. I noticed there was a vacuum leak coming from the manifold area so that’s why I replaced it. No weird smell that I can smell when I drive it. Or when I’m outside of it with it idling. When I replaced the o2 sensors today I disconnected the battery which got rid of the CEL. When I put everything back together and started it for the first time the CEL was gone. I drove maybe 5 miles and then I saw the CEL come back on. Yea a scanner would be nice, but they are expensive. Also the spark plugs that I used were AC Delco 41-103. The o2 sensors I used are the exact same part numbers you used in your video. I also got them from rock auto.

These Colorado's really like to through emissions & fuel system codes. 😆 Did you have any problems with the bolts when you replaced the manifold before?

So messing with the leak again will not help with that issue. It’s too much work for no real gain or not much gain. CEL only came on after replacing spark plugs which I did because owners manual says 100k to replace so I did exactly that. I don’t know man it’s just frustrating. I have spent at least 3k fixing replacing old parts, and I don’t want to mess with the truck anymore.

Hi! Thanks for your comment. When you say "the intake sensor wires" which sensor do you mean, specifically? There are several. Depending on what engine you have and what year, they may be in different locations. I recommend the following videos for more information on the various sensors. As I mentioned before, mine is an '07 with the i5 engine. Yours may be slightly different. Hope these links help show the locations of some of the various sensors: How to replace MAF and MAP sensors in a Chevy Colorado: kzbin.info/www/bejne/hJitp3-fjNiXqc0 2007 Chevy Colorado - Replacing camshaft position sensors, P0340 & P0341: kzbin.info/www/bejne/pYHci6SuZdZlirM How to replace air filter, VVT solenoid, and other maintenance on a Chevy Colorado: kzbin.info/www/bejne/i2KXZJqEj9GKmLc The MAF, MAP, camshaft position sensors, and VVT solenoid are some common "sensors" you may need to replace on a 1st gen. Other common sensors include the oil pressure sensor and crankshaft position sensor. Those are both much lower, located on the passenger's side and the driver's side of the block, respectively. However they are not typically referred to as "intake sensors". I think you're looking for one of the above (in the links). If you'd like to comment back with more specifics of your particular vehicle I may have more suggestions for you. Good luck!

@@thiagolemao hi! Do you have one camshaft position sensor on the engine or two? Look very carefully. In 2004-2007 the engines had two camshaft position sensors. In 2008 and up they only had one sensor. It's a very common problem that people ask "where do I plug in the second sensor" when they do an engine swap from a truck with a newer engine to an older, or vice versa. Is it possible that someone swapped the engine in your vehicle with an earlier engine? You may only have one wire but two sensors, depending on what year the donor engine came from. Unfortunately I can't help much beyond this, but I know the issue with the sensors is very common in swapped motors. Are you getting any check engine codes? Which ones?

I recall seeing a few years ago something called "Supersparkz" that would replace the springs in the coils with solid metal and thought about doing something similar at the time, but (fingers crossed, knock on wood and all that), I've never had any issues with them. Of course, now that I say something, they'll probably go bad next week. 😉 How many miles do you have on yours? Any major issues?

@@CompTechMike Just coming up on 100K. Prior to me owning it, It was a park ranger truck in Ohio. Great service record but how many idling hours is unknown. Want to change the plugs and was concerned that when I pulled the coils it might mess them up. A set of aftermarket coils are pretty cheap, so I was considering changing them at the same time. Biggest problem is rocker panels are cancerous. I'm getting quotes of 3K. Yikes! Never was into body work. A set of replacement panels are only about$150.

@@michmvp yikes! That's cool that you know the history. I think you should be okay to re-use the existing coils if you want to save money, but since you need to remove them anyway it's as good a time as any to replace. 😉 That rust can be pretty bad on our trucks. The rockers, as you noted, I'd also check around the back of the frame near the leaf springs. Boxed frame can trap water (no drain holes in bottom) and rust from the inside out. Good luck, hope she gives you many more miles!

Hi! Thanks for commenting on my video. I might be a little bit biased, but mine has worked great. 215k miles and no major issues beyond the usual maintenance and wear parts. Nothing I couldn't fix myself. The 3.7 solved many of the major problems with the head the earlier 3.5 engines had, and was a solid engine in many of the GM vehicles of this time period.

@@CompTechMike for sure !!! Recently, I bought a 2018 Kia Sedona with a "essentials package"... and it's killing the battery. It ran great for two weeks and then I had to replace battery ( went to AutoZone they check it, charging system and starter were just fine...dead cell in the battery). So...new battery and two days later dead battery again. Went to AutoZone again and this time everything checks out good. I'm trying to track down the power drain. The key fob won't open up the sliding door either but it opens and closes normally with a slight door tug and closes normally pressing the "close button" on the van body. I'm thinking maybe a bad solenoid that receives impulse signals from the key fob ? Now, I have to disconnect the battery cables every night til I solve the problem. Any ideas? In one of your responses you suggested a "Chevy Colorado Truck Club". I'm wondering if they have one for the Kia Sedonas ? Thanks again....and You have a variety of interesting videos !!!

Do you have a video for changing the gas filter, i have a 2004 gmc canyon
@CompTechMike
@CompTechMike 4 жыл бұрын
Hi! I'm afraid I don't have a video for that, but on an '04 it should be pretty easy to do. The fuel filter is located inline of the fuel lines running up towards the front of the vehicle, usually near the left side (driver's side) near the parking brake cables. Once you slide underneath just feel for the lines around the tank and follow them up, should be pretty easy to locate. You may need a couple open end wrenches or pliers to undo the disconnects. Keep a bucket and rags underneath to catch any spills. Also, take the fuel cap off first can help remove some of the pressure from the system, making it less likely to drip. You're lucky, after '06-'07 they started putting the fuel filter inside the tank. Only way to change it on the newer trucks is to drop the tank and pull the pump. That or remove the bed so you can reach it from the top! 😫😭😭

@CompTechMike
@CompTechMike Жыл бұрын
Hi Andrew! Thanks for checking out my video. I try not to give specifics like this because the 1st generation Colorado trucks had six different engine options between 2004-2012. The measurements may not be the same for each of them. I just show the process, always recommend people consult with their owner's manual for exact specifications of their specific vehicle. That said, assuming you are using high quality replacement plugs, they recommend not gapping them because the iridium center electrode is more brittle than most metals and can be fractured or broken. The ground electrode (the hooked one) is actually platinum and can be bent carefully, but to be honest I’d just leave them be. They should be preset. Measure before install. If one is significantly off, return or exchange it. 😊

@CompTechMike 2 жыл бұрын
@@iFrostiy Hi! Thanks for the comment. It sounds like you know what you're doing. Could there be something lodged in the socket, maybe, preventing it from fully contacting the plug? My spark plug sockets have a rubber "bushing" (for lack of a better word) inside them to prevent them from dinging the top of the plug. Sometimes that slips out of place. Maybe stick your pinky finger up inside the socket and see if maybe you have that, and it's slipped down? Only other thought would be if someone stuck a radically different-size spark plug in there and you need to use a different size socket, but I doubt that is the case. Check for the rubber thing and let me know. I just did another plug change on my '07 a couple weeks ago. 231,000 miles and still running great. Good luck with yours!
