So when im accel. sometimes i get a quick hesitation or detonation at around 2600 rpm. Not sure how to explain it really, its like hitting a wall for a millisecond. Only happens sometimes, but more often then not. I have done a tba with vag even though it said it was ok already. Any ideas would be sweet, no codes and i can only feel it in first and second gear, mostly first less in second. Anyone whose had this problem or has any idea what could fix it would be sweet.

 

I have the same problem, but mine happens in 3rd gear under a heavy load(Like being in 3rd around 2000 and then going WOT and it starts shaking a little around 3-4000 and then clears out.. Any suggestions?
Happens usually in 3,4,5th

 

same problem but when I'm in first

 

i get the same thing in 2nd around 2200-2600rpm

 

my ex's 1.8t used to do this (it was mostly in 2nd, sometimes in 1st) under a rather heavy load, we pulled the codes and it turned out to be a misfire...

 

i bet its spark plugs...

my car does this now too recently... now ta\hat i think about it, i did a sea foam session not too long ago too... hmm

 

ditto! every time I've seen an otherwise unexplained hesitation or shutter, it has been poor sparkplugs.. pull them and check them out.. its free to check / cheap to replace, unless you know they are in good shape i would start there

 

X2 ^^^

 

It's an 01 1.8T... Check to make sure your coil packs are the newest ones (should have a date of 2008 or later). If they are dated 03 or earlier, swap all of them out.

And make sure you don't pay more than $35 each TOPS. Some dealers are gouging over $50 each when the Audi list is $33 or so.

 

hmm... just changed my spark plugs (just did it like 6 months ago, but thought it could have been causing the issue since i did a seafoam recently...)

but that didnt help! i had gapped my plugs to .30 initially when i installed them 6 months ago, and when i took them out they were ALL like .24 approx....

i did loose the gapper i used the first time and had to stop and get a new one from oreilleys... think using a different gapper could be so different ?! well that wasnt the fix anyways so im just rambling i guess...

any other suggestions? im getting hesitation at completely random rpms under moderate acceleration... think its my MAF needing cleaning? or what?! this is starting to get to me since i have no CEL's
