stuttering problem at more than half throttle
I have an 2004 A4Q 6spd 1.8t, I have changed all four coil packs, service regularly, but still am having a problem with stuttering when under hard load and more than 3/4 throttle. Have no idea what could be causing this.
The air bag light comes on intermitently and then goes off, dont know why. any help would be greatly appreciated.
Thanks
Stephen

RE: stuttering problem at more than half throttle
Any CELs? If so is it flashing? Get your codes read at autozone (free) then post them in the B6 area otherwise people are just guessing as to whats wrong and thats really not alot of help. Sounds like a misfire but can't be sure w/o codes.

RE: stuttering problem at more than half throttle
sorry its been awhile to get back, I've changed all the coil packs, bought them at Autosport Werks. Changed all the plugs. The code was for the small emission leak, the valve on the passenger side of the engine, changed that. The next thing is a Timing belt change, I guess I'll do it myself. Many years working on cars just never on one of these, if it was domestic I could tell you.

Hi All
I have the same stuttering issue on my 2.0T B8 with 147000 on clock. I have had spark plugs and coil packs replaced, and my regular mechanic has recommended I go to dealers because he could not find any issue. I am thinking Lamba sensor, or airflow sensors or vacuum are possible errors. Any other suggestions.

I have the same issue on a 2010 A6 3.0T. New coils & Plugs, New mass air flow sensor, new everything. Drives great then shakes like a 3 cylinder. Stop, shut it off for a minute or two, starts fine and runs great! little while later same scenario all over again. New gas filter, air filter All original Audi parts. What gives. 2000.00 invested thus far and have had it only two months.
My third audi but it may be my last.
