MY 1990 ISUZU TROOPER, STANDARD, INTENSIFIES ITS REVS IN IDLE SUDDENLY. SOMETIMES IT GOES UP AND DOWN, UP AND DOWN... AND I CAN SEE HOW THE TEMP GAUGE RISES QUICKLY. MY MOMENTARY SOLUTION IN SUCH CASES IS TO STOP THE CAR AND SHUT OFF THE IGNITION AND WAIT, SOMETIMES THIS LEAVES ME SOME MINUTES UNTIL IT STARTS REVVING UP AND DOWN AGAIN. NO INJURIES SO FAR, BUT I HAVE NOT BEEN USING THE TRUCK MUCH FOR THIS SAME REASON. I WOULD LIKE TO KNOW WHAT ID THE CAUSE SO THAT MY MECHANIC CAN SOLVE IT. *NM

PLEASE INITIATE A RECALL OF THESE VEHICLES AND FORCE ISUZU TO REPAIR THESE DANGEROUS DEFECTS AT THEIR EXPENSE, NOT THE CONSUMERS'. PLEASE TAKE ACTION ON THIS EXTREMELY DANGEROUS SITUATION. I WOULD APPRECIATE YOUR INSTRUCTING ISUZU TO CONTACT ME WITH INFORMATION ON WHERE I CAN HAVE MY TRUCK TOWED TO BE REPAIRED. IT IS NOT SAFE TO DRIVE IT. SEVERAL GARAGES SAID THEY CANNOT DIAGNOSE…
