(Thread Starter) |   Not Ranked : 0 score  Intermittent knock/rattle/chatter at idle (youtube) As the title suggests, I have an intermittent knock/rattle/chatter from the area around the hpfp or it could be coming from behind/under the engine. In the video you can hear that it comes and goes, and I can really only hear it at idle, especially after the car has been driven for awhile. Fuel pressure holds at WOT, experiencing slight increase in knock retard spikes up to 3 or 4, at low rpms, once or twice per drive, but car drives and sounds fine besides at idle. Mods: CS SRI, CS hpfp internals, CS TMIC, Cobb AP Any help or ideas would be much appreciated. |
