Hi, I have a problem with my 2001 durango slt 5.9 liter. I have 58,000 miles on it. Just within the last couple of months, when driving at speeds 50 and above with the cruise control set at 65 or any speed above 40, the seems to want to increase its speed, when that happens, the rpm hand move up about 100 or 200 rpms, and then settles back to where it was while at the speed that had been set. It is very prominet in the cruise control setting, but will also do it while out of cruise control, and it isn't consistent. It doesn't do this every time you drive it, but is becoming more frequent. I sure could use some help on this matter.

 

Check out the last post in this thread (it sounds similar to your situation):

It might be your Throttle Position Sensor (TPS). Apparently, these don't always throw off a code upon failure. It is located on the driver's side of your throttle body. They cost about $45 at Napa / $25 at the Zone. Two torx screws hold it on. It should take less than 15 minutes to switch one out.

I'm switching mine out tonight to see if it cures my surging/bucking problems (at idle and under light load from 1400 to 2500 RPM's).

Good luck!

 

Hi, and thank you so much for your fast response. All of the suggestions that I've received has been aimed directly at the TPS. So I will start there and if that fixes it, I will let the forum know, and if by some chance it doesn't I will let the forum know. Thanks again for your help.
