Back fire issues
Hi people I have a Subaru wrx turbo,
I have recently fitted a sti engine and it also had
Simtek Ecu fitted and mapped by steve stimpson.now recently
When I boot it the car seems to miss fire and starts backfiring,
Any ideas as to what it could be it seems to only do it if I really boot it and
Backfires terribly any help would be appriciated regards ben

The car runs absolutely perfect when I don't boot it but once I start booting it then it starts to get worse,normally around gear 3,4,5 . I'm sure when the car was being mapped I was told the plugs ain't the correct ones they were Halfords plugs but would this cause that problem it's a backfire,splutter but you can hear it banging away. I don't think it's head gasket tho

Coilpacks most likely. Pull them off and look for cracks, replace with new age coilpacks or V3/V4 single coil and wires if you plan to keep the car for a while. There are threads on Scoobynet and Nasioc about the conversions.
