We have found the the cylinders are doing all sort of sh*t like droping of from cylinder 2 to 3 to 5 and so on. And yes we have tryed all the things we thought it would of been e.g spark plugs, coils, injectors, head gasket etc.I have heard of ecu's of stuffing up before so hope is that Link to comment Share on other sites More sharing options...
