CHill3103 Posted March 23, 2022 Share Posted March 23, 2022 I have a 2007 impreza 2.5 wrx. I've been having an issue with jerky acceleration/ no acceleration at the 4000 revs mark. Steady acceleration past 4000 revs doesn't jerk but when I put my foot down it jerks like crazy and sometimes doesn't accelerate. I have cleaned throttle body/changed maf sensor/replaced fuel pump/changed air filter and no joy. Any help would be much appreciated.

Tidgy Posted March 29, 2022 Share Posted March 29, 2022 Sounds like its hitting boost/fuel cut. is it decatted and mapped for it? best bet get it on a dyno and see whats what, could be as simple as a boost leak somewhere. Quote Link to comment Share on other sites More sharing options...
