ALS XJ

OK: I have a '92 XJ Laredo 4.0 w/286k. Here was my issue:
Jeep would start fine...about 1 minute into idle, it would sputter (spew massive hydocarbon out of the tailpipe), then rev itself up to about 1200rpm. This process would repeat itself over and over. When driving, if I mashed the throttle, it would sputter and almost stall (pulling out into traffic got very dangerous). I replaced the TPS, IAC, completely removed the TB, cleaned it and replaced the gasket. Nothing.:bang: I then moved on to a Complete Tune-Up (Cap, Rotor, Plugs, Wires and Acell Super Coil). Would not go away.:sign0181:
THE CURE: O2 SENSOR!:beer:
A quick 5 min. fix...Jeep is back to normal...idle at 750rpm solid.
I hope this helps somebody out there!:D
