no throttle response

The other day i was driving along not getting on the truck at all and the SES light came on and i lost most of the throttle response. i pulled over and shut the truck down and restarted it and it was fine. the past couple of days i have been driving it with no problems. Any ideas?
Thanks
Andrew

sounds like the throttle position sensor. My truck did the exact same thing. you have to replace the whole throttle peddle assembly unless something new is out since I did mine.

I had a similar experience this morning - pulled out onto the main road and there goes the throttle response down to almost nothing. Engine was still warming up, but I wasn't on it at all. I was able to get the rpms back up but then it did it again. Finally got it back and was good all the way into work, but now I'm nervous. Also noticed a puff of bluish-white exhaust as it was happening. Is this still likely to be the throttle position sensor???

basically just sputtered out and RPMs just dropped to idle then lower. I got off the pedal, then back on it, off, on and it gradually came back up. Did it twice yesterday morning.

I changed out the CPS last night and the truck started and ran fine this morning. Hoping that's all it was. But I thought that when a CPS croaks you were dead in the water and not intermittent though?

It was raining out, but i have been driving it for a week without any problems. someone mentioned to me it was because of the 18k mod, so i have had that off and had no problems. CPS is relatively new, but i know they can take a **** at any time. thanks
