A6 p0305 misfire, heres what I have tried.
Please read all details of what I have already done!
1996 A6 2.8 with 204k bought the car with multiple misfires 4-5 and random, did sea-foam, spark plugs and coil pack seemed to get better.
Still misfire on 5, I pull the plug wire and it has good spark, I pulled 4 and 5 fuel injectors cleaned, and have great spray. Did compression test, 200 all the way across.
Just a little bit ago I pulled to do the compression test after warming up the engine for a couple of mins and the PLUG WAS WET, I put it on the intake, started it up and it sparked great right away. Why would it be wet? but yet spark? it was all wet, therefor I am getting fuel, that rules out bad injector wire.
What would make it spark but so off time that it does fire?
Oh also, this may be important right after I do the sea-foam (done it twice) it runs amazing! like super fast throttle response seems like nothing is wrong, then like 10 seconds later it slowing starts misfiring again. This is a noticeable misfire like its not firing at all! I cam pull the plug or injector and it runs the same.
Again no bs common answers please aka coil pack, wires ect.
Thank you!
