Hi all I am sort of new to audis. I have an 05 with 57k miles with the 3.2. I purchased it in fla and drove it back to ohio without a hitch. And ran great for about the first week i was back here. Im starting to get a sputtering/hesitation/miss (feels like my car is going over a bunch of bumps) right around 1500-2000 rpm. Now if i step on that gas and do a hard acceleration it goes away. It also only happens after the car has been warmed up. It also begins to idle slightly rough as it warms up. When its cold none of these things happen.

I changed all the plugs, and the coils were clean and looked fine. According to the local audi dealer it already had the coil recall done. I believe i know what arching is, but im not sure of what to look for on the coils to tell if arching has taken place. the coils looked fine to me.

I thought it may be something with throttle or O2 sensor since it only happened with very light gradual acceleration but didn't happen with heavy acell. then i thought it may be the coils sense it only happen with the car heats up.

So im all over the place here, any ideas?

thanks again.
