I have a 2000 z28 a4 which is pretty much stock, and i have this slight hesitation right around 2500-2800 rpm on acceleration and i have not a clue what it is, i definately notice it in second gear when i'm about half throttle and up, its not really a bog just a hesitation that last about half a second or so..
Thanks for the help

I had this problem once & it turned out to be a dirty MAF sensor.
LOL, one of the joys of owning a K&N air filter.
Take some electronical cleaner & Q-tips & clean it really well.
Make sure the small wires are clean & free of oil.
Just be careful not to break them.

Yeah, K&N air filters have a tendency to get oil on the MAF sensor.
I had a very similar hesitation at around 2500 rpm.
Get a can of CRC electronic cleaner. It comes in a red & white spray can.
Soak the MAF sensor thoroughly & clean the wires off with Q-tips.
It worked like a charm for me.
Good luck man.

Just so people know.......be careful touching the tiny little wires with a q-tip.......it can break the wire and then you'll be buying a new MAF. If you get a can of CRC MAF cleaner and just blast the spray directly into the MAF through the screen, real good, it will clean everything off that might be there.
