Hesitation under full throttle

Postby lanley v3 » Thu Oct 21, 2010 1:01 pm

last couple of days my car has been acting up.
Under WOT (wide-open throttle) acceleration after 3000rpm and peak boost, it hesitates slightly and i can feel the revs slow down.
Only happens between 3000-4000rpm, after that it pulls normally again.
I changed spark plugs last night, checked for boost leaks recently, checked for error codes. Nothing :(
Anyone have a clue what's wrong? :?
Dunno what else to check...
Thanks

don't think so. I would feel it throughout the rev range. It is more pronounced between 3000-4000rpm. Sucks balls.

Put some octane booster and see if it does it again.
