97 Ford Hard Start, Rough Idle and Business Operations Pt1

[@calholli]

The leak around the IAC makes a lot of sense. That's why it was having trouble idling, but still ran fine with you drove it.

[@SchrodingersBox]

yes that would make sense for sure except the leak and the IAC showed to be so minimal it would have impact on drivability. i was certain at first it was a vacuum leak, but smoke test showed it wasn’t.

[@sanctealphonse4510]

Hey Matt, love the show! One thing I do for work when I have to access a technical website w/ lots of info (such as your VIN lookup website) is print the page to a PDF file and stick it in the job folder. That way I don't have to access the website ever again if there's something I forgot to get. The Opera browser has a 'save to PDF' option which will save the file to one continuous page w/ everything on it unlike the page breaks that sometimes mess things up on a PDF file printer. Just thought I would throw that out there in the off chance you didn't know about it.

[@SchrodingersBox]

Oh I definitely do that!! for example when I find a wiring diagram (especially one I pay for off ALLDATA or whatever) I absolutely download it and save it for future reference

[@jeremycurtisisgay]

I didn't realize there was so many videos on KZbin about auto repair. It's such an easy field, especially now with all the data you have access too. Plug in your little device and it gives you the issue, sort of. I just didn't realize there was so much interest in Auto Repair?! I do believe it was a very difficult field back in the day, though. You had to really understand and control the machine. Now, you just learn the system, values with your own process and it's actually very very easy.

[@SchrodingersBox]

Well unfortunately if you ever actually get on of these little devices you will very very quickly find it actually is nothing even close to how you described it. here is an example: you have a cranking no start. your little device shows a cranking engine RPM of 250. you see a cam crank signal correlation of 1.0. fuel injector pulsewidth is 50ms and map indicates a voltage of 1.5 with MAF of around .20lb/s. what’s wrong with the car that it won’t start?

[@jeremycurtisisgay]

@@SchrodingersBox I mean, of course you have interesting times but by and large it gets very easy. Obviously, I was being being snarky with the scan tool remark, but I stand by my statement of it being easier now. Even though you are a DIY guy and only take in select issues, you know im telling the truth. Maybe once a week something is a little challenging. The mechanical part is more difficult than the electrical/electronic part for someone who knows the system. Your car has a crank no start issue. Have it towed in and I'll take a look at it and have you back on the road.

[@jeremycurtisisgay]

@@SchrodingersBox I can tell by your videos that you have the knowledge of a mechanic who does it all the time, so you have to be honest. Modern vehicles are easier to work on

[@SchrodingersBox]

you never answered the question. what is your next step given the data I provided in the example. I mean this is easy right? it’s a modern CAN vehicle and I provided the basic scan tool data. so what’s your next move? You said “This is easy” so where is your answer?

[@jeremycurtisisgay]

@@SchrodingersBox Dang, I don't know why you are being so defensive about my comment and opinion. I still Stand by my comment 95% of issues are easier today with the data than before.. yes, it can be difficult and challenging at times but most of the time it's straight forward. In your hypothetical car scenario, I'm not sure man. So many factors to this. Im not sure what I'd do. I guess, first thing I'd do is take the information you gave me and put in back of my head. I'd then confirm the complaint. I would then do all the easy, fast stuff that I pretty much always do. Usually it's sorta narrowed down as far as direction on those situations without really digging into any data. If that doesn't work,I would probably just then from easiest to hardest manually check everything I possibly could that would cause a crank no start. Probably start throwing parts at it, starting with recommended 100k mile O2 sensor. replacement. If that didn't work, I'd recommend the owner take it to someone who knew how to interpret this "Dang ole Computer stuff".

[@rickgreen9619]

I don't think in any of your videos it showed the location of the neighborhood. Beautiful area.

[@SchrodingersBox]

well thank you!! yes it is a nice area in a new home development as of just 2 years ago in Parker, Colorado.

[@abubakarisadiqueibrahim481]

I also like the neighbourhood.

[@calholli]

@@SchrodingersBox You really shouldn't Dox yourself like that. Next time just cut away until you're down the block, that way you can at least hide what exact house you live at. It's easy to find out exactly where you live now. We know your city, state, we know your street and we know the exact house that you backed out of in this video. Make sure you don't do this again in the future. It's too easy for people to target you.

[@CarlWilliams-u3y]

An Actron CP9690 has code-connect to diagnose codes. Special tests checks misfires. Normal is 0. Erase the codes and recheck. Check fuel trim. See if the exhaust is stopped up. On record test, with the koeo and engine cold, look at the cts reading. See if it's accurate according to outside temperature. If it thinks it's much warmer than the outside temperature, that can cause a lean mixture. If it reads too low, that can cause a rich mixture. One guy posted a video of his truck hard starting. He replaced everything. I suggested the cts. That was it! South Maine Auto uses it to check emissions readiness on test drives. A Launch x431 checks history report. A Launch Creader elite can be used on the road.

[@TheVintageEngineer]

Let me go ahead and tell you that the IAC valve has a vent port that will look like a vaccum leak. Well it is a leak but it’s a known metered leaked. So if it is coming out the “button” looking cap on the IAC, it’s fine. I’m waiting to see the diagnosis. Wild guess to throw in the pool, but I’m going to go with recessed valve seats on exhaust valves. It’s a common occurrence/not commonly known issue on these older SOHC cast iron engines. Because this engine uses hydraulic lash adjusters, I can see this contributing to bad idle when engine is cold. Still big guess based on the little info we have at the moment.

[@robertchaffee5662]

Check the fuel rail pressure right away! Then individual spark plug, spark test! Then compression test!

[@PhillyDee215]

😉I agree, definitely much easier to work on a car when your the only one that's been working on it

So far, so good. Cool smoke machine 👍🏻, looking forward to more info on it.

[@SchrodingersBox]

More to come!

[@sanctealphonse4510]

I was surprised to see that smoke machine on your show. Makes me feel good about my purchase of the same one LOL (except mine hooks up to compressor). I got tired of using my homemade smoke machine consisting of a large popcorn tin (you know those ones you get on Christmas) with air fittings attached and a smaller tin inside w/ a baby oil soaked rag and a lit charcoal briquette. I was likewise impressed with the quality and everything you get w/ the package. Now if they would make one w/ a flow meter that would be especially awesome. I was thinking about ordering a medical flow meter on Amazon for $20 and plumbing it in - IF I ever need one.

[@SchrodingersBox]

hahaha I hate to say it but you totally would have liked the pump unit better lol. As cheap as it is- get one for christmas and wait for my discount code coming soon!!

I wish you had shown how you had inserted the smoke nipple into the Mass Air Flow. I also wish you had explained what you meant by a vacuum control leak. What is it? Where does it occur in the engine? What do you have to do to fix it?

[@helloitsme4139]

Scotty Kilmer would have had this fixed already with $4200 in parts and a $5000 scan tool, wave your hands around 👏fire the parts cannon, Boom fixed. And that’s how you rev up your engines

[@SchrodingersBox]

lol I didn’t know he had a scantool hahaha. i figured an actron code reader.

[@HaroRider03088]

Scotty has been a mechanic for 74 years.

[@abubakarisadiqueibrahim481]

I love Scotty but I love this guy more. He takes you through with less editing and simpler explanation. Scotty's video is cool but much editing. I actually started watching Scotty way before I came across others. I must admit it did me lot good but Matt is giving me more into details. They both on different level with same results. Getting cars fixed.

[@bigdaddymak1439]

Parts cannon is just fine because it needed them anyway!! 🤣🤣🤣🤣

[@calholli]

The old man is fine.. I still watch him because of the random auto- news that he brings up. I usually skip over the repair advice or the car reviews. I learned enough about scantools from Scottie to know that I needed to know more-- then I found this channel, Ivan, Eric O, and Wes.... and now I've graduated youtube scantool mastery school... and I'm learning about pico scopes more and more now. You gotta love the free info on the net. It's all out there, you just have to look

[@DirtbikeDad]

I get a code for running lean on bank 1. It’s a ford ranger 2.3 4 cylinder 5 spd. Also has a hanging idle. Before all this the only code I had was thermostats stuck open

[@SchrodingersBox]

stuck open thermostat would cause rich codes. you have a pretty obvious lean condition - pretty simple.

[@DirtbikeDad]

@@SchrodingersBox what’s the obvious fix. If it was stuck closed it would overheat ! Never does never did The idle does drop down but slowly. Pushing 300.000 miles

[@SchrodingersBox]

Not obvious fix. Obvious diagnosis. Fuel trim diagnostics are straightforward for this one because it’s confirmed lean.

[@DirtbikeDad]

@@SchrodingersBox I have a basic lil plug in scanner how do you repair the fuel trim tho ? Wouldn’t that be in the programming aspect of reprogramming ecm ?

[@SchrodingersBox]

you don’t repair the fuel trim. you repaired the cause of the fuel trim. a basic scanner is more than sufficient. do the basic fuel trim analysis as shown on the video and then fix the cause of the condition. thenthe fuel trim correction will go negative confirming the fix and you know it’s resolved.

Ignition on the exhaust gives it higher torque in low gears.
