Owner report 10018510 · 2003-05-11 (May 11, 2003)
MY 1990 ISUZU TROOPER IS EXHIBITING DANGEROUS REVVING AND DROPPING OF THE IDLE. THE TRUCK ACCELERATES WITHOUT WARNING AND IS IMPOSSIBLE NOW TO DRIVE SAFELY. IT IS MY UNDERSTANDING THAT THE ECU IN THESE TRUCKS IS FAULTY DUE TO MANUFACTURING DEFECTS. I FURTHER UNDERSTAND THAT THOUSANDS OF OTHERS HAVE THESE PROBLEMS. 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…

Owner report 10180877 · 2007-01-27 (January 27, 2007)
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

NHTSA campaign record ↗90V167000 · Power Train:Automatic Transmission
Reported: 1990-09-20 (September 20, 1990)
PUTTING IN MORE TRANSMISSION OIL THAN SPECIFIED CAN CAUSE OIL TO BLEED THROUGH AIR GROOVE ON TO THE EXHAUST MANIFOLD IF OIL TEMPERATURE RISES.

Remedy: REPLACE OIL LEVEL GAUGE AND NOTIFY OWNERS TO USE ONLY THE SPECIFIED AMOUNT OF AUTOMATIC TRANSMISSION FLUID.
