i have a 96 audi a4 quattro and i cant figure out what the problem is... when i ccelerate sometimes it fells like it boggs alot then just picks up and is fine it does it all the time baically and i was just wondering if anyone has any ideas... maybe a super clogged fuel filter cause the pump sounds fine no buzzin...?

 

almost kinda like theres a block somewhere and i kinda floor it to blast thru it...

 

At what point does it 'pick up? 2k, 3k, 4k rpm? Could be a manifold change over valve problem, dirty MAF, clogged air filter, etc...

Does it do it when your trying to pass? Could be a tranny downshift problem...

Need more info.
