Hello folks,
I am a new Crossfire fan and owner
- got my crossfire about 3 months ago. Its a 2004 Limited Coupe with 115k on it. Love the drive and the look of the car, pretty much everything except some minor annoyances of which some are understandable at this mileage (some cabin rattling noises, around dash, side and rear gate windows, also wind noise between door window and roof, and fogging headlight).
Anyways, my major problem is the knocking sounds that can be heard at low engine speeds. The sound decreases as rpm's increase and disappears completely at around 800 rpm. Its very hard to pinpoint where its coming from, maybe a little louder under the car. Also, sometimes after driving, especially aggressively, it would go away even when stopped, at the light for example, where it idles at those low rpms. I just changed the oil, thinking maybe the previous owner put something wrong in there. I used 0W-40 Mobil-1 and Mann fleece filter. One thing I want to note is that the valve covers are leaking some oil - bad gaskets?
If only there was a way to raise the idle speed I will never hear the annoying knocking
but with today's electronic throttle bodies I don't know how it can be done unless programming the ECU.
Regards
