I HAVE A 1995 GRAND CHEROKEE LIMITED WITH THE 5.2 V8. IT RUNS GREAT MOST OF THE TIME HOWEVER IT OCCASIONALLY IDLES ROUGH WHILE DRIVING. IT ACTS AS IF IT WANTS TO DIE AND STUMBLES LIKE SOME OF THE CYLINDERS ARENT FIRING. THERE IS NO CONSISTANCY TO THIS AND IF I MASH THE GAS IT GETS UP AND GOES. HOWEVER WHEN I SLOW DOWN FOR A LIGHT THE IDLE JUMPS ALL OVER THE PLACE. IF I STOP THE TRUCK SHUT IT OFF AND LET SIT A WHILE IT WILL RUN FINE AGAIN. I HAVE CHANGED THE IDLE AIR CONTROL MOTOR, THE PLUGS WIRES CAP AND ROTOR. I ALSO REPLACE THE EGR VALVE AND TRANSDUCER, O2 SENSOR AND HAD FUEL SYSTEM CLEANED. NONE OF THIS HELPED I ALSO CHANGED FUEL FILTER TWICE. SOME TIMES THE IDLE WILL BE SMOOTH BUT IT WILL SURGE FROM 500 TO 1200 RPM AGAIN SHUTTING OFF HELPS THIS GO AWAY

sounds like the TPS could be bad. This will cause the idle to hunt
