Surging RPMs 2001 Ram

[cokeman]

I have a 2001 Ram with 82,000 miles 5.2 engine, The RPMs will surge 200-300 while idiling or driving down the road. Tried fuel additives, changed plugs. Any thoughts. Thanks

I have seen on several other forums that the solution is to have the dealer re-flash or re-load the computer firmware on the truck. Apparently this will resolve the issue as the mechanics will only check the obvious and state that they cannot find the problem. It should not cost you more than $50-70 at the dealer. Hope this helps!

its an easy fix . i have 01 ramm 1500 with 318 90,000 miles i bought the truck brand new only 22 miles on her when i got it. but, just replace the pvc valve every oil change (also run lucas in the oil , trust me she'll run like a raped date!!
and clean you air filter ALOT !!
