this has probably been asked a million times... but anyway. I have a 2002 wrx, on idle it sounds like its slightly misfiring, well its not smooth in any case. ANy under acceleration, theres either a mega lag or its holding back, and you really have to rev it to get anything out of it, rolling road power is fine though its just under acceleration.
Whats the script for sortin this out do you rekon? MAF? coilpacks? its been serviced with new plugs etc so i think somthing is on its way out
ANy advice you guys can give would be ace
oh and is it common for MAF's to go on wrx's?
