What is wrong with my truck?

[jeepcjsrule]

Alright,



I Bought my truck approx 3 weeks ago, today while cruising down the interstate at 70 mph the rpm's would surge up about 200-300 rpm's and then go to normal( only lasts a few seconds when surging) It did this a few times when I droped back to 65mph it dident do it any more and I never had it happen til I pushed it up to 70 mph today. I pushed it up to 80 to see if it still would do it and it did the same thing surged up about 200-300 rpm's.



I have been reading lots of posts to learn as much about my truck as I can and my best guess is the problem has somthing to do with the Throttle position sensor, Am I correct?



Will this hurt anything if I dont get it fixed right away?



I would appreiacte any help you all can give me.



Thanks alot!

Mike

Throttle position sensor is the problem-do a search on it and you will have more info than you know what to do with

I haven't had any trouble with mine yet, but it guess you can gtake them off & clean the contacts. Kinda costly to replace.
