Need Help
I have 02 GTO with Mafless tune. The rev Limit is set at 6500 rpm. After fitting a 3000rpm Hi stall and giving it a service (plugs, fuel filter, etc) the car started to misfire at around 6000rpm and continues to misfire when backing off the throttle until it dies out. when starting it again it still misfires and the clears up.
Was told it was fuel related and have since changed fuel pump to Walbro 260L/hr and have had injectors cleaned. No change still the same.
Misfire only starts when revved and continues till it dies out.
Any help appreciated.
I have also replaced pvc pipe as I found this to be broken at the rubber joints.
