weird idle problem
SO when I went to start my truck yesterday, it turned over and immediately revs up to 2500-3000Rpms and just sits there for about 30 seconds and then slowly, and I mean slowly, starts to drop. It does this on cold start ups and warm start ups.
I put a new TPS and IAC in it about a year ago, so I don't believe that's the problem. Any ideas?

Just had the same problem a month ago and after spending money on a new IAC, MASS air flow (tried cleaning them too), O2 sensors, spark plugs, and fuel filter, it turned out to be a ripped vacum line that runs along the head covers. But it also drove poorly and idled bad. So not sure if your truck runs fine when its warmed, or during operation. My truck also would come and go but eventually it gets really annoying, Hopefully this helps.

Hey, Well The picture above (Previous post) was the problem I found that was causing my hesitation and bog, that elbow in the vacum line was ripped. It was a gas hog for a little but once the vacumm line was fix it was fine. Have u replaced your fuel filter? Is the check engine light on?
