Guest jamesn Posted May 27, 2006 Share Posted May 27, 2006 My car is stuttering real hard around 3500 RPM. It won't go until I let off the gas then gently rev it then it will move again. I change my NGK 6097 to Denso Iridium spark plugs, fuel pump, fuel pressure regulator and it doesn't seem to help. Anyone have any ideas???

TLicense Posted May 27, 2006 Share Posted May 27, 2006 Coil packs? Could be something to do with the way the AFR goes jumps up and down at the crossover between turbo's 1 and 2, so could be O2 sensor? Link to comment Share on other sites More sharing options...

Lucifer Posted May 27, 2006 Share Posted May 27, 2006 Firstly reset your ECU and try again. You will find out how to so that on here. I have seen this when one of the actualtor pipes has split or poppes off. Link to comment Share on other sites More sharing options...
