Hi,
My 2000 JGC is a gasoline engine with 230k's, and very well maintained (oil changes on schedule, recently changed plugs, new radiator, run mid grade and higher fuel alternately, etc.)
Recently it started sounding more like a diesel when it starts up in the mornings.
The noise is noticeably loud for the first 45 seconds to about 1 minute, and then starts quieting down gradually there after.
After about 3-4 minutes, it sounds normal again.
Does anyone have an idea what this could be?
Thanks.
