my astra 2.0 litre sri 16v 1999 64k 137bhp keeps revving its self without me touching the peddle, goes up to around 3000 revs, when i touch the accelarator it conks out, have to turn engine over for a good minute to re start it and then it runs fine again as if nothing wrong, might not do it again for weeks then bang, same again, changed fuel pump, fuel filter, air filter, idle speed control valve, {stepper motor} put some injector cleaner in, did 400 miles recently, didnt miss a beat, thought it sorted but conked out again at traffic lights other day, anyone else had similar problems?

firetrap is like an extra small box in the air pipe to carb to trap flames on a backfire
