I have a 1999 Limited V6 4x4 automatic with 122,000 miles.
Over the last year I have had an engine noise that has progressively gotten worse. After I sit in traffic for over 5-10 minutes depending on the temperature outside, hotter=faster, I get a bad engine rattle when accelerating at 1800-2000rpm, particularly uphill, like getting on a onramp to get on the interstate.
If I go on the interstate for a while and come off the interstate then the noise is gone, but in city traffic the noise only goes away only if I go over 2000 rpm for 15-30 seconds. If I start out driving on the interstate for over 15 minutes then I never seem to get the noise.
The noise goes up and down with the accelerator. I find that I am unable to reproduce the noise when parked in neutral and revving to 1800-2000 rpm, but I figure it is engine related because it is accelerator dependent.
Any ideas?
