- misfire on this vehicle. has p0305 and p0200. engine runs rough and check engine light blinks. this video will show how to diagnose a p0305 and diagnose to see if it can be a failed injector, open in harness, or bad ecm signal.
this might have been filmed on an iPhone but your explanation, coverage, and diag skills are 10x better than most of these professional YT mechanics!
This was a really good video bro, I ran a scanner diagnosis and found it gave me a p0200 and p0303 which basically should indicate that poppet valve on cylinder 3 is fried. I'm thinking of just replacing that poppet.
great info 13.5 ohms! but you didn't have to remove the upper intake manifold to check the resistance just unplug the connector
Bro i have the 2007 Chevy Silverado 4.3 Its a nightmare!!! Its slowly coming back to life, i have just been stuck for a while now.. until I saw your video
I wouldn't call myself a mechanic but I know what to do and not to do to make a vehicle work..
I have p0200 and p0303 cylinder 3 misfire..
I have no idea how to check it like you did but im going to try it if that. Im just not really sure how you did it with the meter. Thanks man!!!
I'm here to try to help. Whatever questions you have let me know and I can try to help in any way
I have the same engine. Replaced the spider injectors, just a couple months ago. And the other day my truck starting running rough. So I scanned it. It said cylinder 3 was missing. So I replaced the spark plug on it bc when I pulled it. It was burnt. And it’s still running rough. Need some advice
The basics will have to be inspected on cylinder 3. Injector pulse, Spark, and compression. New parts can still fail.
I'm currently having the same issue with a 4.3L but mine is cylinder 3...
Any update did you fix it I have same problem with 5
what did you unplug and put on the cowl?
It was the injector that I put on the cowl. Usually they do not come seperate from the spider leg but while trying to remove it from the slot the leg came off the injector and separated from the leg so I put it on the cowl.
Spent $400 on a PCM that I didn't need that my mechanic misdiagnosed. Truck has 290k miles don't exactly know how old the plugs and wires are. I bought new ones and changed them one by one. Then the last plug wire was burnt off not attached to the plug. There ya go though that was the issue but ran good for a bit. Then back to misfiring. I noticed a slight exhaust leaking after acquiring the truck. I was blind too see the last port was missing two bolts. The leak must have made it run lean causing to burn hot. One more trip to replace the gaskets and or hardware for the exhaust manifolds.
