Hey, I am a new member and have really enjoyed the forum so far. I must have been on drugs when I picked my user name though. I have a 93 instead of a 92, but whatever. I have seen several threads on idling but my problem seems a little different. My truck cranks up and idles fine. But after I drive it a short distance and stop, when I crank up again it runs rough. Its usually just for a short time. Like while I am backing out of a parking spot and getting turned into the lane. It doesn't seem to make a difference when I get going. Although I did notice the other day while setting at a red light the rpms fluctuated slightly. I have put new plugs,wires, and cleaned the air sensor. I wondered if I might have gapped the plugs a little close. Any suggestions would be appreciated. My truck is the 4.0 auto extened cab.
 
mine does that too except also when you first start it after sitting too. Been reading trying to find something, but no luck.
