My 94 was doing the same thing, real bad if I had been driving for a wile. I changed all the belts and it hasnt happened again.
#6 of 6 '94 Trooper idles fast by bigskinny

My Trooper's engine (3.2) is recently rebuilt. I replaced all vacuum lines, PVC valve, etc. When I purchased the vehicle the O2 censor was not connected so I replaced it this weekend. It has new plugs and plug wires. I assumed the thing was running in a default mode prior to all this work because it was slow to start, idled fine, but didn't get the mileage I thought it should. Now, with all this work done the idle speed is high. Upon cold starting the vehicle runs at a normal increased RPM. When warm it doesn't change. When driving and the clutch is pushed in the engine will idle up to 2000 RPM then down to 1500 then back up to 2000 RPM, continuing the cycle until I stop rolling. When I come to a complete stop with the clutch in the engine will quickly slow to 1200 RPM. Any thoughts?- « Previous
