I have a 2006 Audi A4 Quattro 2.0 turbo FSI, with 105,300 miles on it. It is throwing codes p0300, p0304, p0303, and p0301. i recently changed the spark plugs and coil packs and injectors. with changing those 3 nothing has changed. Car barely runs at idle and most times will die out. If you give it throttle it will stay running. If you throttle up and give it a some what of a high rev it will backfire and pop. i cant seem to figure out what else it could be.

So far i have done:
oil change
air filter
spark plugs
coil packs
Injectors
gas cap
canister purge valve
camshaft oil control valve
intake manifold gasket
valve cover gasket

Hmm....could it be just bad gas? Not unheard of. Good luck and let us know what you find. Hayabusafalcon.
