I have a 2005 Cabriolet 3.0. The problem that i am having that about 50% of the time the engine does not start easily (excessive cranking of engine before it finally starts and runs rough, but after you step on gas it does not idle rough). It does not matter if the car has been warmed up or sitting overnight. It does not matter if it is cold out or warm out humid or not humid.
The car also has a constant rough acceleration. This happens all the time. I have had the fuel pump replaced and i just had the crankshaft sensor replaced and still the same issues.

The car does not have any check engine lights on either.

Any help would be greatly appreciated

I have an '03 that just recently started running rough during acceleration, usually between 20-35 mph. I'm trying some fuel injection cleaner to start. My brother said it worked for him years ago. Not sure about the starting issue..

Fuel injector cleaner
New plugs
New coils
New crankshaft sensor
New fuel pump

Im thinking that the only items left to change are the fuel injectors and the cam shaft sensors

I really though i would get more help from this forum.

There is usually more action on the Audiworld A4 B6 forum than on the Cabriolet forum. You should try posting there. Good luck.
