FOR THE 93,CHECK FOR VACUUM LEAKS AROUND THE INTAKE AN LOOK AT ALL YOUR HOSES GOING TO THE INTAKE ON THE PASSENGER SIDE,MAKE SURE NONE ARE LOOSE.
92 GUY,SOUNDS LIKE YOUR CABLE MAYBE STICKING,HAVE YOU CHECKED THAT?ALSO CHECK THE THROTTLE LINKAGE THAT THE CABLE CONNECTS TO.DOES IT RETURN BACK TO THE CORRECT POSITION?..ALSO ON BOTH MODEL YRS.THE VACCUM SWITCH ON TOP OF THTE T-STAT HOUSING CONTROLS IDLE ALSO.ESP HUNTING IDLE PROBLEMS.AS COOLANT TEMP HEATS UP THAT VALVE BY-PASSES EXTRA AIR TO HELP IDLE.THERE IS AN IDLE ADJ SCREW.ON THE T-BODY..FIRE-WALL SIDE.THAT YOU CAN ADJ.IT,S FACTORY SET .BUT OVER TIME VIBRATION THROWS IT OFF.YOU SHOULDNT HAVE TO TURN IT MUCH.WHEN THOSE VALVE GO BAD,IT STAY S OPEN AN CAN RAISE THE IDLE LIKE A BAD VACUUM LEAK WOULD DO,AN ALSO LAST BUT NOT LEAST THE PLASTIC INTAKE HOSE RIGHT ABOVE THE HEAD AN EXHAUST AIR INDUCTION,MAKE SURE THERES NOT A HOLE IN IT FROM THE HEAT OF THE EXHAUST.YOU HAVE TO RUN YOUR HAND UNDERNEATH TO FEEL IT,YOU WONT SEE A HOLE,UNLESS YOU TOOK IT COMPLETLY OFF.AN MASS=AIRFLOW SENSOR SOMTIMES GOES BAD,NOT OFTEN,I JUST REPLACED ONE AT THE DEALERSHIP AN IT WAS 700 DOLLARS O.E.THANK GOODNESS THEY DONT GO BAD OFTEN.
