hay guys hope you can help, when i put my foot down with the boost controler on it seems to start miss fireing at about 4000 rpm had it tuned last week at hyper performance and he said it could be the plugs ,, any help will be apreciated ,, i have got new GREDDY plugs but cant get the old ones out ,
im assuming it was fine before the boost increase? as you are gonna be changing plugs,examine the ends of each coil pack under the rubber boots,any splits,cracks-even hairline ones and they need replacing,check where the wires go into them too for splits
the car runs better without it on but it is still lumpy , where are based mate it might be better if you had alook at it ,if you dont mined
sorry just read yer other thread,id check plugs and coils first as a matter of course,there are so many other things it could be- rule them out first as they are easy to check put boost back to std if it ran ok before i see you have piggyback controller,i was advised not to use these and i wouldnt start messing with boost increase unless someone knowledgable was monitoring the engine AFR as you did so... there are some very knowledgable authorities in this dept on here-im sure they can offer a more expert opinion than mine :wink:
good friend off mine works there just give them a ring tommoz sure they can sort it out for you done things for me in the past no probs
Mixture of tired/damaged coilpacks and plugs. You don't need any fancy plugs for 1bar of boost, PFR6Bs will be fine at 0.6mm gap so long as the coilpacks aren't too far gone. I've lost count of the number of times I've had the same problem on that era of car. Andrew...
