i also think its the pecil coils, since i removed the central one, it didnt make any odds to the engine as its was missing/jerking about at idle.... But, i used the old spark plugs to test the pencil coils by removing them and connectign them all to the 3 old plugs, all 3 spark plugs fired when connected to the pecil coils when they were resting on the rocker cover... surely one wouldnt fire if it was defiantly the pecil coils? i havern had the chance to get the car anywhere near a faul code reader, i might take it to the garage tomorrow hopefully.... ive just been out in it now and it was 'just' drivable then about 2mins of driving the engine light started flashing and limited the revs to 2k roughly 20mph, im guessign thats some kind of safe mode?? really hope it is just the coils... it coudl be that it fines but its a really **** spark?
