How To Fix A Misfire Code with Basic Hand Tools | P0300 P0301 P0302 P0303 P0304

[@human1513]

As a licenced mechanic and electro-mechanical engineer tech I say you are an excellent video teacher.

[@sciteceng2hedz358]

Can you explain the compression test? Did he crank the engine 4 times rapidly? Why did the pressure increase in discrete steps? He seemed to gloss over that 🫤

[@Techo1329]

@@sciteceng2hedz358 He just held it cranking until the reading peaked...the pressure builds, it's not instantly at max.

[@KharieTheangelwhosin]

Why would my mechanic replace spark plug but not my ignition coil. My dodge calibe has a p2311 and now I’m fixing it as I watch him. Money down the damn drain. My light wasn’t flickering til he worked on it it was lit but not flickering

[@ianbett240]

Thats grate test done there.I also concider checking if that same coil ,could be throuwing spark out side it..Thats one of random issue i experience with missfire on faulty coil.

[@destihyspicher9589]

I have to say this man is very thorough. Its so insightful and he explains it in a simple way and doesn't leave out anything. This man gives me confidence to work on my own Vehicle. Thank you for the way you teach.

[@CarsNToys]

I appreciate that!

@@CarsNToys I got my honda pilot that been in few shops with the code p0303 and they replaced spark plugs, coils and still have the same issue too check engine vtm-4 and vsa light keeps coming out

What did it end up being?

[@vincentra8849]

@@dansouza6284probably sell the car. And forgot about it.. if it is a high mileage vehicle with not a lot of good reputation. More than likely the engine is shot. And needs replacement. I’m looking for one as well as we speak.

[@jonwilmot5331]

Absolutely brilliant. I'd had an old school go. Then I saw your video. I have exactly that engine and a misfire. Pulled the covers off and did all your diagnostics . I swapped coil packs while engine running. The misfire followed the coil pack. So off to get one tomorrow. Many thanks.

[@pico1991]

Dude, thank you. Your video was ultra helpful in giving me confidence to check all the things. You are well spoken and detailed.

[@AdamFreasier1187]

I second that!

[@odinssun2411]

This is the best diagnosis video I have seen BY FAR. Incredible job sir.

[@LouisGFranco]

Definitely one of the best diy videos I've seen. Short and straight to the point showing every step needed and what do according to results. Pretty much troubleshooting diagram in video form. Really appreciate you making this video.

[@jermwall]

This is an excellent tutorial! I appreciate the overview style of instruction about the topic. Other instructional videos tend to troubleshoot active problems; this approach is fine if I happen to be fixing the exact same problem. Unfortunately, because my problem is usually slightly different than what’s presented in the video, I have to rely heavily on background knowledge and / or piecing together information from multiple other videos. In this video, he outlines the fundamentals and then briefly explains how to troubleshoot and fix the multitude of possible issues. It’s a well rounded and succinct way to explain a topic. I’m working on a dodge v6 engine while he’s working on a Honda 4 cylinder and it’s still the video I prefer. 😅

[@Aaron-hd8ql]

Brilliant video even more briliant explaining how everything can be tested made me want to go out and check mine out just for fun. I am sure getting tired of all the shady mechanics and stealerships we have in this world. Guys like this guy explaining everything in the video is proof that people are still nice in the world and want to help you out instead of stealng you blind which is hard to find. Thanks for such an awesome video from start to finish i felt like i was not lied to one bit and also felt like i learned alot and now feel comfortable to try stuff more on my own then to be ripped off by the stealership or a shady mechanic. Once again thank you for all you do.

[@Techo1329]

Great video mate. One suggestion for coil/spark plug testing...say code is for Cyl 1, swap coils between 1 and 2 and plugs between 1 and 3, if the fault goes to 2 or 3 you have the answer. If the fault stays on 1 you have ruled out coil and plug in one go.

[@BruceD42]

Isn't that what he said at 2:27 in the video?

[@Techo1329]

@@BruceD42 Not exactly, I added a suggestion to rotate the plug at the same time. Two birds, one stone.

[@adriandominguez1494]

What if the problem stays on number 1 what would be causing it ?

[@jsol2480]

We had these codes pop up for 2000 tacoma v6 shortly after changing sparkplugs after purchasing used. Turns out we had broken the tabs on ignition coils that led to bad connection. Connector plug wasnt sitting right causing misfires. We replaced coilpack and connectors too so might as well. Sparkplug wires is next because one tab is broken too and its held on by zipties. Thanks for breaking it down for us!

[@iftikharqureshi654]

[@kizito8888]

It's very important that you do this on a colder engine. The bolts tend to break if you tighten them while the engine is hot.

Wires too. Have messed up spark plug wires pulling them while hot too

Hi everyone I’m a Honda and Acura technician just wanted to say very great video very good explaining the steps yes I recommend people start educating them selfs about there vehicles yes you can check a fuel injector with a multimeter and please wear safety glasses especially if your gonna deal with the fuel system great video you could definitely be an automotive instructor 👍 thumbs up 👍

[@JoseReyes-sf5hd]

Since you're a honda tech, I scanned my car and it said all coils were bad. There was no indication they were going bad. Is that even possible that all coils would go bad at the same time?

Hi! Thank you so much for taking time to make all the videos for us. Please help me. Here is my issue. I just bought a 2003 GMC Sonoma SLS 6 cylinder Truck . The truck shakes/vibrates really bad once started. You can literally see the engine moving and shaking. It shakes throughout the drive and also appears to shake even more when at stopped light. Just yesterday afternoon, i was at a red light waiting to make a right turn onto the freeway. Once light turned green as i was pressing the gas and turning my steering reel it became hard to where i couldn’t turn it normally and literally suddenly just died on me. Thank goodness there was no other car making a right turn on the far left lane because when my truck steering reel became hard to turn the car went toward the left side. I tried few times to start car and it started and i went to the left turn trying to turn into the 7’eleven parking lot, right when i went onto the parking it died again. This time it took more times until car started again and this time when it felt as if the car is starting i gas it to help turn on. Then i drove just across to Oreilly and the worker scanned car and a code on his machine detected Cylinder 2 misfire. Purchased NEW: Spark plug wire set 6 spark plugs Replaced it on car. Still not resolved. Upon checking the MAF sensor was no good, the distributor has a line cracked on the number 2 . Went back to Oreilly: Purchased NEW * MAF Sensor *Distributor Cap & Rotor Replaced on car with those too. Again NOT Fix still showing code Cylinder 2 misfire. I do not want to guess on what it is. Can someone please guide me on what to do next that can fix this. **At this moment writing this comment, i am in the car parked at Oreilly debating what to get. Do i get Fuel filter?

Hopefully u got the assistance that was needed boss, if so what was your issue?

[@thelostshadowofhanzo]

Just a couple comments, for one in my many years experience most vehicles have the relays and fuses for the engine in the engine compartment. Normally the fuse box for the cabin electrics like the lights, windows, door locks, dash, HVAC, entertainment, etc, is in the cabin. Two while doing an OHMs test can tell you if an injector has either a complete open or shorted circuit on the primary windings inside, it will not test if the pintal is moving or if there is a partial break that is causing the injector to not generate a good magnetic field to move the pintal. An injector being mechanically stuck is more common then an electronic fault, which your resistance test with a multimeter will not show. Also you dis not mention the fact of the signal wires or testing the ground connection on either one of those circuits, which could also have a fault. I know what dealers say to test, but true diagnostic technicians know those are often poor testing methods the dealer has in their flow charts. Also you did not do a voltage drop test on either one of those circuits when testing your power feed, which is a superior test to testing for resistance which a wire that is almost completely cut will show up as ok when testing resistance. If you are going to show stuff like this, please show good testing methods instead of the bs that has been standard in the automotive community for too long.
