1989 Isuzu I Mark

THE ECU HAS CAUSED ERRATIC ENGINE BEHAVIOUR AND COMPLETE ENGINE FAILURE LEAVING US STRANDED ON NUMEROUS OCCASIONS. MECHANICS HAVE BEEN UNABLE TO RESOLVE THE ISSUE AND THE VEHICLE HAS BEEN UNTRUSTWORTHY OVER IT'S ENTIRE LIFE. MANY TIMES THE IGNITION SYSTEM HAS FAILED IN TRAFFIC WITH OUR BABIES IN THE CAR LEAVING US STRANDED IN THE HEAT. THIS UNIT SHOULD BE RECALLED. IT WOULD BE NICE TO HAVE SOME OF THE HUNDREDS SPENT ON MIS-DIAGNOSIS, MOTEL BILL'S AND TOWING SERVICE, ETC. REIMBURSED BY GM/DELCO -ISUZU. PLEASE CONTACT ME IF NECESSARY. DT

THE COMPUTER IN THIS CAR CAUSES FOR AN EXTREMELY ERRATIC IDLE. WHEN THE VEHICLE IS FIRST TURNED ON, THE IDLE SPEED IS NORMAL AND STEADY FOR ABOUT 5 TO 10 SECONDS, AND THEN ALL BETS ARE OFF. SOMETIMES IT GOES UP, SOMETIMES IT GOES DOWN, RANGING ANYWHERE FROM NEAR-STALL TO 3000 RPM. IT DOES THIS EVERY TIME THE CAR IS TURNED ON WHEN COLD, ONLY OCCASIONALLY AFTER IT IS WARMED UP. I WOULD TRY REPAIRING IT, BUT I HAVE A GREAT DEAL OF EXPERIENCE WITH THIS ENGINE/ECU COMBINATION, AND ALMOST ALL OF THEM (INCLUDING DEALER-SUPPLIED REPLACEMENT ECUS, WHICH ARE FRIGHTFULLY EXPENSIVE) DO THIS. THANKFULLY, I AM AWARE OF THIS PROBLEM, SO WHEN I AM IN CLOSE QUARTERS WITH A COLD ENGINE, I KEEP MY FOOT ON THE CLUTCH, READY TO SPRING INTO ACTION. THE CAR, DESPITE IT'S MILEAGE, HAS BEEN VERY WELL-TAKEN CARE OF, AND HAS A GREAT DEAL OF POWER. ONE TIME WHEN THE POWER HIT (IN FIRST GEAR, COASTING WITH MY FOOT OFF THE GAS), IT ACTUALLY SPUN THE TIRES. SPINNING THE TIRES WITH YOUR FOOT OFF THE GAS IS NOT WHAT I WOULD CALL A SAFE CONDITION, ESPECIALLY GIVEN THAT MOST OF THEM DO IT. WEREN'T ALL THE AUDIS RECALLED FOR SOMETHING LIKE THIS BACK IN THE 80'S? PLEASE CONTACT ME IF YOU WOULD LIKE ANY MORE INFORMATION.*AK
