#13 of 14 RPM'S FLUCTUATE WHILE IDLING by unicorn747 Sep 17, 2008 (9:01 am)
what would be causing my rpm's to go up & down while my 2001 gmc jimmy is just idiling? there's no problem while i'm moving- just when i'm idiling. it's got a 4.3 v-6 vortec engine in it. Replies to this message: nljewell (Dec 10, 2008 1:14 pm)

Replying to: unicorn747 (Sep 17, 2008 9:01 am) My 99 Jimmy does the same thing only when my heat is on. A few years ago I was out of state and my alternator took a crap, had it replaced at a dealership, and that's when it started. If you find out why e-mail me at nljewell1104verizon.net. Thanks.
