1991 Isuzu Stylus Owner Complaints

TL* THE CONTACT OWNS A 1991 ISUZU STYLUS. WHILE DRIVING APPROXIMATELY 50 MPH, THE VEHICLE WOULD STALL WITHOUT WARNING AND THEN RESTART. THE CONTACT MENTIONED THAT SOMETIMES THE VEHICLE WOULD FAIL TO START FOR DAYS. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHO DIAGNOSED THAT THE FAILURE WAS DUE TO A FACTORY DEFECT. THE MECHANIC EXPLAINED THAT THE MANUFACTURER SPRAYED ANTI HEAT SPRAY ON THE CIRCUIT BOARD, CAUSING EXCESSIVE SHRINKAGE OF THE BOARD DURING THE SUMMER AND WINTER WEATHER. THE MECHANIC ADVISED THAT THE SHRINKAGE CAUSED THE STRUTTER TO SEPARATE, RESULTING IN THE FAILURE. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 100,000. THE VIN WAS NOT PROVIDED.

THE CAR SURGES WITHOUT WARNING WHEN IDLING. THIS APPEARS SPORADICALLY AND UNPREDICTABLY. IF THE CLUTCH IS ENGAGED, THE CAR WILL LURCH FORWARD AND STALL. IF NOT ENGAGED, THEN THE ENGINE SUDDENLY REV'S VERY HIGH. AT TIMES THE ENGINE IDLES HIGH FROM START CONSISTENTLY FOR 5 OR MORE MINUTES AFTER STARTING, REGARDLESS OF WHETHER THE CLUTCH IS ENGAGED OR NOT. WHEN THE ENGINE REVS HIGH, THE CAR LURCHES AND DRIVES ERRATICALLY WHEN IN MOTION. I HAVE BEEN TOLD BY OTHER ISUZU STYLUS OWNERS WHO REPORT SIMILAR PROBLEMS THAT THIS IS AN ECU ISSUE AND THAT THE PART SHOULD BE REPLACED, AS IT IS A DESIGN FAULT.

MY REGULAR MECHANIC INDICATED THAT THE PROBLEM WAS ELECTRICAL. SO I TOOK THE CAR TO A DEALERSHIP. THEY INDICATED THAT THEY COULDN'T FIND A PROBLEM, BUT ON THE WAY HOME IT STALLED AGAIN. WHEN I SLOW DOWN OR COME TO A STOP THE CAR WILL SHAKE AND IDLE HIGH AND THEN STALL. IF I PRESS THE GAS AND KEEP THE CAR REVED UP IT WILL EVENTUALLY RETURN TO REGULAR IDLE, BUT SOMETIMES STILL STALLS.*AK

THE CONCERN WE ALL HAVE IS WITH THE UNPREDICTABLE ERRATIC IDLE. WHILE SITTING AT A STOP, THE RPMS WILL JUMP FROM A STEADY 900 TO BETWEEN 2000-3000 UNEXPECTEDLY. THERE IS NO WARNING. I HAVE HAD TWO 90+ ISUZU CARS AND BOTH HAVE HAD THE SAME SYMPTOMS. AS THEY WERE BOTH MANUAL TRANSMISSIONS, I WAS NOT AS CONCERNED WITH THE POSSIBLE SIDE EFFECTS OF THIS SINCE WHEN IT WOULD OCCUR I WOULD EITHER HAVE THE PARKING BRAKE ON AND BE IN NEUTRAL, OR THE CLUTCH WOULD BE ENGAGED. OUR MAJOR CONCERN IS WITH HOW THIS AFFECTS THE AUTOMATIC TRANSMISSION VEHICLES. THE VERY POPULAR GEO STORM IS INCLUED IN THIS GROUP OF CARS, SINCE IT SHARES THE ENGINE AND ELECTRICAL SYSTEM OF THE ISUZUS IN QUESTION. THERE HAVE BEEN CONCERNED NOTES FROM OWNERS OF THESE CARS WITH THE AUTO TRANSMISSIONS WHO HAVE BEEN SITTING AT A LIGHT WHEN THIS WOULD OCCUR AND SUDDENLY THEIR CARS WOULD LUNGE FORWARD. LUCKILY, THESE DRIVERS HAVE BEEN ABLE TO CORRECT THE ACTIONS OF THEIR CARS BEFORE THERE WAS ANY SERIOUS DAMAGE. WE HAVE FOUND SHORT TERM SOLUTIONS TO THIS PROBLEM, BUT THE REAL CULPRIT IS THE COMPUTER, AND AT $600+ EACH TO REPLACE, MOST OWNERS PASS. HOPEFULLY YOU WILL NOTE OUR CONCERNS, AND INVESTIGATE THIS PROPERLY. PLEASE FEEL FREE TO CONTACT ME IF YOU NEED MORE INFORMATION OR FURTHER EXPLANATION. THANK YOU FOR YOUR TIME, AND CONCERN. HOPEFULLY WE CAN RECTIFY THIS PROBLEM BEFORE ANYONE GETS INJURED. *AK
