I have a mk4 gold agu engine, the other day whilst driving the car 'backfired' then turned off. Now when i start the car it stalls and turns off pretty much straight away unless it has been left over night then it may take 30 seconds to stall and everytime after that it will stall straight away.
If i unplug the MAF then it will run but obviously this is not good. I tried another MAF sensor from another AGU which i know is fine and that did the exact same thing.
I took my spark plugs out and number 3 was covered in oil, I have replaced both the inner and outer gaskets and replaced the spark plugs but it still does it.
I am in desperate need of help or advice!
