I had the same issue, drove me freaking crazy. #1 do the PCM update, #2 adjust the cable, #3 flush the tranny, each one of those helped me a little bit, now I dont have an issue at all.

 

Hey Guys, Update...... I went to the Auto parts store to just pickup an Brake switch just to try it out first but of course they were out of stock. So I asked them if the have an TPS and they did for $35. I went ahead and bought it, installed it and reset the PCM. Well, to my surprise so far with about 100 miles on my full tank, the surging seems to be GONE..... That seems to have fixed it, Awesome (Trying not to count my chickens before the hatch, LOL). Thanks Guys. Only time will tell, but IT'S GONE for NOW..... It's was starting to Drive me Crazy and the Wife was already past that point.....

Thanks Again,

Derek.

 

you don't happen to have an o2 simulator on your exhaust do you? I had a surging problem with my transmission in my 1998 1500 shortly after i installed an o2 simulator. The dealarship replaced my computer with no fix, replaced the tranny with no fix and made a call to a transmission shop where they were tipped off to the o2 simulator causing the problem. A new o2 sensor was put in my exhaust and the simulator disconnected and the problem fixed.

Wow, no kidding Jake? All that work and all it was - an o2 sensor type of issue?

 

I was having problems similair to this but it was sputtering and surging at the same time. It was like I kept letting off the gas and back on (you know how it downshifts and/or tc lockup) I turned the o/d off and it kept sputtering and surging. TPS? I later got red and STOMPED the gas! Fixed it.... WTF? Now it runs great like before but I am curious as to how long it will take for this to happen again.
