My truck now has 99,000 miles on it. For the last 10,000 or so I have a problem where it want to idle at 1000 rpm, but not all the time. As time has gone on it now does it almost all the time. My first though was the TPS, but if you ride the clutch a little bit to drag the rpms down it will idle normal, if it was the TPS I would think it would jump back up. No check engine light.

Also seems as it has a little bit of a miss when it idles fast.

Any ideas?
