1991 ISUZU IMPULSE

I HAVE A 1991 ISUZU IMPULSE AND IT'S HAVING ECU PROBLEMS. MY MECHANIC SAYS IT NEEDS TO BE REPLACED. I SEE THAT THIS IS A RECURRING PROBLEM WITH THESE CARS, AND IT SHOULDN'T FALL ON THE SHOULDERS OF THE CONSUMERS. *AK

CAR RACES ENGINE BADLY IN THE SUMMER WHEN TEMP OVER 80 DEGREES-WONT IDLE. *AK

THE CONSUMER STATED THAT THE VEHICLE IS EXPERIENCING THE SAME IDLE CONTROL PROBLEMS AS STATED IN PREVIOUS RECALL REGARDING THE ELECTRONIC CONTROL UNIT. *YH

THE CONSUMER STATED THAT THE VEHICLE IS EXPERIENCING THE SAME IDLE CONTROL PROBLEMS AS STATED IN PREVIOUS RECALL REGARDING THE ELECTRONIC CONTROL UNIT. *YH

THE SYMPTOMS OF THIS FAULT ARE MOST NOTABLY ERRATIC IDLE, IDLE REVVING AND DROPPING, IDLE DIPPING OFTEN WITH ENGINE DYING, IDLE HANGING HIGH ABOVE 2,000 RPM, AND ENGINE DYING OR STALLING FOR NO REASON WITH NO TROUBLE CODES. THESE SYMPTOMS WILL OFTEN ONLY OCCUR IN WARMER WEATHER AS THE METAL CIRCUITS OF THE CIRCUIT BOARD SEEM MOST VULNERABLE TO SHORT CIRCUITS AT SOLDER CRACKS WHEN THE TEMPERATURE WITHIN THE CAR IS ABOVE 80 DEGREES FAHRENHEIT. IN TEMPERATE CLIMATES, THE SYMPTOMS MAY FIRST SHOW THEMSELVES AS SOON AS THE WEATHER WARMS AND PLAGUE THE OWNER ALL SUMMER LONG, ONLY TO SUBSIDE IN THE FALL WITH THE COOLER WEATHER AND THEN REAPPEAR THE NEXT SPRING.

THIS IS A REOCCURRING MANUFACTURER DEFECT. PLEASE ISSUE A RECALL ON THESE ENGINE CONTROL MODULES. *AK

AS THE WEATHER IS GETTING WARMER THE ENGINE REVS AND DROPS UNCONTROLLABLY. THE CAR ALSO STALLS AT ANY SPEED. I HAVE HAD IT EVEN STALL ON THE HIGHWAY. I HEAR THIS IS A COMMON PROBLEM ON THIS PARTICULAR TYPE OF ECM UNIT, PLEASE CHECK INTO THIS FOR ME. IF I HADN'T TAKEN A DEFENSIVE DRIVING COURSE I COULD BE DEAD RIGHT NOW. *AK

THE DEFECTS ARE DUE TO THE IMPROPER MANUFACTURING OF THE ECM MODULE OF THIS VEHICLE. THE SYMPTOMS INCLUDE AN ERRATIC IDLE WITH THE IDLE REVVING UP AND DROPPING TO THE POINT WHERE THE ENGINE DIES. THE IDLING WILL JUMP UP TO 2000 RPM, LINGER THERE UNTIL I BLIP THE THROTTLE, SOMETIMES UP TO 3 OR 4 TIMES. ON ONE OCCASION, WHILE DRIVING ON THE FREEWAY AT 65MPH, THE ENGINE BEGAN TO STALL WITH THE IDLING MOVING ERRATICALLY, AND THEN SUDDENLY THE CAR WENT COMPLETELY DEAD IN THE MIDDLE OF THE FREEWAY. LUCKILY, I MANAGED TO COAST OFF TO THE SHOULDER WHERE I REMAINED STRANDED FOR OVER FOUR HOURS. WHEN DIAGNOSED BY THE DEALER, THERE ARE NO TROUBLE CODES PRESENT. IT WAS SUGGESTED TO ME TO REPLACE THE IGNITION MODULE, PLUGS, WIRES, COIL PACKS, CAM ANGLE SENSOR, AND VARIOUS OTHER COMPONENTS DUE TO THE REASON THAT THEY WERE THE ONES CAUSING THE PROBLEM. OBVIOUSLY, THE PROBLEM WAS NOT FIXED AND MY WALLET WAS LIGHTENED BY ABOUT $500. THE DEALER STATED THAT THIS IS "NORMAL" FOR THIS TO HAPPEN. I D

THE CAR WILL FOR NO REASON STALL, EVEN AT HIGH SPEEDS RESULTING IN A LOSS OF POWER STEERING AND BRAKES. THIS IS THE SECOND ONE THAT I HAVE OWNED, AND THE OTHER ONE HAD THE SAME PROBLEM. I WAS MAKING A LEFT HAND TURN, WHEN THE CALL STALLED, AND CAUSED A LOSS OF STEERING. A PEDESTRIAN WAS WALKING ON THE STREET CORNER, WHEN MY CAR SMASHED AGAINST THE CURB, JUST BARELY MISSING HIM. IT'S REALLY SCARY WHEN THIS HAPPENS ON THE HIGHWAY. I WAS TOLD THAT THE ECU IS DEFECTIVE IN EVERY IMPULSE/STORM EVER MADE. WHY WASN'T THERE EVER A RECALL? ARE WE WAITING FOR SOMEBODY TO BE KILLED FIRST?

WHEN CAR WARMS UP YOU CANT DRIVE OR IT WILL STALL. ONCE WARMED UP IT WILL NOT START. I SAW AN ARTICLE ON THE ISUZUPERFORMANCE WEB SITE THAT SAID OTHER VEHICLES HAVE THIS PROBLEM. IT ALSO STATED THE REASON FOR THIS PROBLEM IS A FAULTY ECU COMPUTER MADE AND INSTALLED BY AC DELCO. I WISH I WOULD HAVE HAD THIS INFORMATION BEFORE I WENT OUT A BOUGHT PARTS TO TRY TO FIX THE PROBLEM MYSELF. IF ITS THE COMPUTER, THERE IS NOTHING I CAN DO ABOUT THAT ON MY OWN. A RESPONSE ON THIS ISSUE WOULD BE GREATLY APPRECIATED. THANK YOU. *AK

THIS IS THE 2ND IMPULSE THAT I HAVE OWNED, AND I THOUGHT IT WOULD ONLY HAPPEN TO MY FIRST ONE, BUT THIS ONE IS THE SAME WAY. WHEN IT GETS WARM OUT, THE ENGINE HAS IDLING PROBLEMS. THEN OTHER IMPULSE I HAD (1990) DID IT FROM DAY 1 AT 55000 MILES. *AK

NO SUMMARY LISTED FOR ABOVE VEHICLE. *AK

NO SUMMMARY LISTED FOR ABOVE VEHICLE. *AK

THE VEHICLE FAILS TO RUN AFTER IS WARMS UP. I HAVE CONTACTED SEVERAL MECHANICS AND WAS TOLD THAT IT IS A COMMON PROBLEM. I WAS TOLD THAT THE MANUFACTURER USES AN INSULATING SPRAY ON THE ECU THAT CAUSES IT TO SHRINK AND BRAKE CONTACTS IN THE UNIT ITSELF. THIS IS VERY DANGEROUS IN THAT IT HAS LEFT ME STRANDED ONCE ALREADY AND WITH LOOSE CONTACT IT MY CAUSE A FIRE. I DO NOT EXPECT THE MANUFACTURER TO REPLACE THE UNIT FOR FREE. I BOUGHT THE VEHICLE USED SO THEY DID NOT MAKE ANY MONEY OFF OF ME BUT SOME HELP WOULD BE NICE. I FIND THEM RESPONSIBLE SO THEY SHOULD LIVE UP TO THERE REPUTATION OF QUALITY. *AK

NO SUMMARY LISTED FOR ABOV EVEHICLE. *AK

ECU HAS ERRATIC PROBLEM. WILL PUT THE CAR INTO HIGH IDLE AT ANY GIVEN SPEED AND WILL NOT RESET UNLESS CAR IS TURNED OFF AND RESTARTED. REPLACE ACCELERATOR CABLE AND RESEATED ECM SEVERAL TIMES TO NO AVAIL. TRY RESETTING THE ECM TO GET THE CAR OFF OF HIGH IDLE WHILE YOU ARE IN TRAFFIC. *AK
