[@zombiechris4813]

Could also be an intake manifold vacuum leak. I changed my spark plugs and coils, and it was still doing the exact same thing it did before. Come to find out my intake manifold vacuum hose was very loose. Could have saved $200 by simply pushing it on all the way and applying a hose clamp.

Okay I have a 2012 Honda civic LX, 171k miles, I have changed the plugs to ngk, still ran terrible, new ac Delco coils, ran even worse, it threw a code of coil A Wich is piston 1 and I changed it and it helped but still runs like crap!! Now my next step is the injector , because this whole time I'm throwing p0304 misfire and plus are new and so are the coils, the car starts , but man does it vibrate and it's loud! Sooo my last opinion is a faulty injector, I mean idk I'm at my wits end I have a new baby and I need my car running...So i smell fuel out my tail pipe and i smell fuel in my oil , faintly, i can only assume i 4 is stuck open and flooding fuel in piston 4, its my only conclusion , I cannot afford this car down anymore, if I out these new injevtors in an it still runs the same. I'm going to lose it, 10 days on this piece of crap...I need help , it's 155 bucks to take it to Honda lol yeah right

[@CaseyHealsMe]

I am not throwing a code for a bad injector....But I did take em out to clean them and injector 4 was closed and spewed out yellow stuff, I can only assume hydro carbons, but anyways It was a 9V battery operation lol but it was messed up bad, thought after I cleaned it up it would run better but nope, so I can assume that the injector runs worse cause it has more volts from the car battery on it,..I hope it's my injector, I think they are the original ones as well

What are the specific codes? Are you able to read live data?

[@a69strat]

I have a 2010 Ford Escape with 4 cylinder 2.5l. Code P302. #2 cylinder misfire. Spark: I checked the coil and it is not bad. Pulled it up and I can hear it sparking. Swapped with the coil in 3rd cylinder and no change. #2 still misfire. Compression.: I pulled out the plug of #2 and checked compression. It was 135 lbs. I checked compression of 3 and 4 cylinder, both also 135lbs, So not mechanical/valve/rings. I put in new plugs while checking compression and no change, not plugs. Fuel: I purchased and replaced fuel injector in #2 cylinder, no change. Engine misfires, but not a completely not firing. Meaning if I pull the the wire connector out of the coil, the engine does drop, a little, but not jumping like if if pull it out of another cylinder. Same if I disconnect the lead to the fuel injector. So if it is not spark, not compression/mechanical, and not fuel, what else should I check?

[@VicManBRA]

Is it possible that an engine overheat + fuel injector problem due to fuel quality + fuel pump with low pressure(now replaced) could cause an iridium spark plug to last shorter?

[@SirD31V1D]

Yes, it is a type of metal with a good electrical conductivity. If the cooling system cannot keep up with the constant detonation of fuel by keeping it with normal working temperatures (usually between 185F and 220F) then your iridium spark plugs may degrade faster. Cooling flush + Spark Plugs replacement + A bottle of SeaFoam Fuel Additive every oil change would maintain your vehicle very well.

[@mummaistvan7320]

Does your RPMs go up and down when idle? Have same problem. My RPMs when idling, 650 rpm - 700 rpm. I cleaned all the carbon off EGR, MAP, cleaned my MAF sensor, & will be doing my throttle air intake valve. Took the throttle out and soaked it in break cleaner to get carbon build-up off. Make sure if you decide to clean your MAF, use MAF SENSOR cleaner. Wires are delicate. Did you use OEM spark plugs, the brand, gap, your Manuel says? I have used Seafoam for years. Has kept my fuel injectors clean. Look at your spark plugs. Is gap correct, are they dark brown, black only on half, or the entire top? I made the error of using Bosch with my SUV. Only half on top was black after a month. Replaced all with OEM. Air filter clean? Gosh can be numerous things. Usually the spark plugs. Good luck. You don't want to be buying parts and still not running good. If able, try cleaning first 😉

No.....bad info. It is rarely the fuel issue when consistly misfiring. If a new plug or plug wire does not reduce or remove the issue the next likely step is to..... Compression check. Anything less than 20 lbs reading on any cylinder indicates valve issues which, means the heads have to come off. any good shade tree mechanic knows this. Poorly done video dude.

[@mariewallace149]

I agree, I definitely figured it was the fuel injector system. My daughter has my hammy down equinox 2012 and it just started to run crappy. It would shake periodically like having a seizure, sometimes hard to start, and very bad on gas mileage. I told these issues to my ex-husband prior to giving it to my daughter especially the fact that I was getting maybe 10 miles a gallon. He kept ignoring my complaints and just saying that oh it gets better gas mileage than my work truck haha. Are you serious?!! Anyhow, I gave it to my daughter and now she's stuck with all these issues... So I'm hoping that it is just a matter of changing the spark plugs and I am a true believer. When changing spark plugs always change the coils!! Why do a job 50% when you can do it 100%?. My ex-husband said to me yesterday. It's not the spark plugs because they don't need to be changed unless the vehicles 150,000 mi?? Really every video I watch or link I click on keeps bringing me back to changing the spark plugs and the coils.... So I had her oil change today and asked the mechanic if he could put it on the computer due to the check engine light staying on - and he came back letting me know that there were several misfires and he insisted that we change the spark plugs and coils. Haha I wish I knew that he was going to say that to me because I would have had my phone on voice record. Then play it back to my ex-husband. Oh I meant to mention he is a master mechanic for Chevy for the first part of his life meaning he retired there as a master mechanic So he worked for Chevy starting in the late '70s and retired there early 2000s as a master mechanic. So as he finished laughing at my face when I said it could be just bad spark plugs, it very well could genuinely be that issue. For the sake of cost I hope it is as little/big as bad coils/spark plugs. 🙏🙏

OEM ones do the same thing. if i didn't pass slow people it would never misfire. the air filter is also new. the engine has been replaced twice so its not that either unless the thing is just lemon trash. replacing the engine and still getting the problem means its not the fuel injectors because those come with a new engine. the only thing i haven't replaced that has anything to do with engine control is the ECU/PCM and that very rarely causes the issue, and its expensive to replace for ""try and see"
