I was thinking coils to start with but then they usually break down at higher rpm, plug gaps maybe? or wastegate?? no leaks in intercooler piping, throttle body could need a clean but was done about 6 months ago..low rpm- could it be vct.?im heading to see bruce in next week or 2 as it also has a 2 sec rattle at start up.. possibly chain guides..

Sounds like he downgraded you and charged ya thinking you wouldn't know any better. The previous ones you had woulda been out of an F6 if they were 42lb. They also would have been greenStandard ones are about 20lb Link to comment Share on other sites More sharing options...
