HELLO, i have a 2002 durango. once in a whileit will drop rpms .Mostly when were at a stop. any ideas. thanks

 

it may be that your tranny needs a little adjustment, it may just mean that you need a tuneup. We need a lil more info about recent history with teh vehicle, and maintenance. What kinda mileage you have. basically just write us a short story about your Durango.

 

well, it has 67,000miles 2nd owner it had 58,000 mi when i bought it 18 months ago.extreamly clean. i put on a k&n cold air intake. i change the oil on time never over 500 mi.idles great 99% of the time just goes from idle to around 1200 rpm but only in drive at a light or drive thru.thanks

 

forgot to mention it has the4.7l

 

Ghog, I recently had the same problem on mine. Same engine in mine. It was a vacuum line that had become disconnected (check engine light did not come on). Check those lines and make sure one did not come disconnected.

Hi guys,

Just a case study:
I had similar issues(2003, 4.7 liter). I seafoamed her (very cool smoke) and settled the idle out a bit 600ish rpms. I cleaned the TB, TBI and IAC. Dirty, but negligable effect. Then I replaced the original plugs with the factory Champion copper plugs (RC12MCC4, gapped @ 0.040). The plugs coming out were VERY clean, but the electrodes were very worn, gapping @ 0.075.
Result:
Smooth as silk idle @ 850 rpm's.[sm=yeahsmile.gif]
Hope this helps...
