Hi their peepz
I do aplogise if this has already been covered.im new to this forum but im pulling my hair out over this issue.im not a mechanic so I dnt know much tech.i know basics.i have a 1998 impreza wrx turbo jap import. When im driving the cars fine upto about 4500 rpm then as I continue to accelerate more up the rpm the car 'jerks' if thats the right term. Can anybody help me on this? One local said it could me maf sensor and someone else said its ure 02 ( lamda sensor). The car is de-cated and has apexi air filter on.
Could it be the fact that ecu needs reset
anothe thing is that when im parked at trafic lights and i start moving im driving along all of a sudden it feels lyk the cars stopped accelarating then out of knowhere it starts to accelarate again.
I would appreciate if someone could enlighten me on this
