Hi, i own a 1993 WRX import and it hesitates badly at high revs. it only started happening after i fitted a HKS induction kit but i ve recently had a new clutch fitted and now the engine check light comes on and off. when the light is on the car hesitates twice as bad. Has anyone got any ideas as to what could be causing it.

Cheers

Steve

sounds like fuel cut or dirty boost solenoid hoses.

 

Sounds like the MAF
