is it at cold start or all the time?
1-check your vac..lines.
2-clean EGR.
3-you might be running rich...(not as in money)...but the again, your acceleration would not be as peppy....
the guy with the kenwood unit never got in touch with me. Therefore, I picked up someone else's radio...I did not mean to purposely hijack this thread...I just Thought that if an Item has been out for quite some time and no one claims it...we should, at least, move on or have a secondary...
I snatched something from him and he got the zune....leaving the kenwood unit untouched....but if you like I can find something else to put up.(humpleg)
