1991 Geo Storm Problems

TL* THE CONTACT OWNS A 1991 GEO STORM. THE CONTACT STATED THAT THE VEHICLE STALLED WHILE SITTING AT A TRAFFIC STOP. THE VEHICLE WAS TAKEN TO THE DEALER HOWEVER, THEY WERE UNABLE TO REPAIR THE VEHICLE. THE MANUFACTURE WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 40,000.

7 MONTHS AND 5 REPLACEMENT ECUS ON MY 1991 GEO STORM GSI, AND STILL HAS DANGEROUS ISSUES OF STALLING ON HIGHWAY AND WHEN PULLING OUT INTO TRAFFIC. THE PROBLEM IS THAT BETWEEN 1985 AND 1995, AC DELCO USED A INSULATIVE SPRAY ON THE CIRCUIT BOARDS IN THESE ECUS/COMPUTERS WHICH SHRINKS OVER TIME WHEN EXPOSED TO WARM AND COOL TEMPERATURE CONDITIONS, SUCH AS THE NORMAL CONDITIONS THAT AN AUTOMOBILE IS SUBJECTED TO. THE SHRINKING INSULATIVE SPRAY CONTRACTS AND PULLS THE ELECTRONIC COMPONENTS FROM THE CIRCUIT BOARD, BREAKING SOLDER CONNECTIONS AND CAUSING SHORTS. 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. GM KNOWS ABOUT THIS FAULT IN THEIR AC DELCO ECUS/COMPUTERS AND HAS EVEN GONE SO FAR AS TO INCLUDE SUPPLEMENTAL INSTRUCTIONS ON HOW TO TEST FOR SHORTS AND BROKEN CIRCUITS IN THE ECU/COMPUTER TO THEIR TECHNICAL LITERATURE, THOUGH THEY REFUSE TO REPAIR OR REPLACE THE PROBLEM AT THEIR OWN EXPENSE. GM WENT FURTHER AND BEGAN USING A DIFFERENT INSULATIVE SPRAY ON ALL OF THEIR ECUS/COMPUTERS IN 1996, THOUGH THEY DO NOT USE THIS NEW SPRAY ON THEIR FACTORY RECONDITIONED ECUS/COMPUTERS FOR THE GEO STORM MODELS. *TR

1992 GEO STORM MANUAL TRANSMISSION. WHEN ENGINE GETS HOT ( SUMMER MONTHS ) ENGINE IDLE INCREASES TO 2,500 - 3,500 RPM. MUST USE FOOT TO PULL UP ON ACCELARATOR. CAR BEGINS TO OVERHEAT LURCHES FORWARD. CAR ALSO STALLS WITHOUT WARNING. HEARD IT HAS TO DO WITH FAULTY ECM. VERY DANGEROUS SITUATION. *JB

THIS IS THE 2ND ECM CONTROL MODULE IN 2 YEARS. . .BOTH WERE NEW WITH ONLY A YEAR WARRANTY. . .PROBLEM ONLY SHOWS UP IN THE SUMMER. *AK

DURING WARM WEATHER THE VEHICLE'S THROTTLE WILL STICK AT 2000. THROUGH MY RESEARCH I HAVE FOUND THIS TO BE THE FAULT OF THE ECU. IT IS A VERY DANGEROUS THING TO HAVE YOUR THROTTLE STICK. DT

VEHICLE WOULD INTERMITTENTLY LURCH FORWARD WHEN BRAKES WERE APPLIED. DEALER CONTACTED. FEEL FREE TO PROVIDE ANY FURTHER INFORMATION.*AK

WHEN VEHICLE SWERVED TO KEEP IT FROM HITTING A DEER, THE FRONT END WENT INTO A IRRIGATION DITCH, AND DRIVER'S SIDE AIR BAG DID NOT DEPLOY. VEHICLE WILL BE TOTALLED *AK

VIOLENT DEPLOYMENT OF AIR BAG PERMANENTLY INJURING EYE OF CONSUMER. (ATTORNEY FOR CONSUMER).

THE DATE & MILEAGE ARE ONLY FOR THE MOST RECENT OCCURENCE. IT STARTED LATE APRIL 2001 AT ABOUT 70,000 MILES; I'D BOUGHT THE CAR USED THE PREVIOUS SEPTEMBER & IT HAD DRIVEN OK THROUGHOUT THE WINTER. THE PROBLEM HAS BEEN HAPPENING OFF & ON EVER SINCE. THE CAR WILL BE GOING 55 MPH OR MORE; ABOUT 5 OR MORE MINUTES AFTER STARTUP (IT VARIES), THE RPM GAUGE/IDLE SUDDENLY DROPS TO 0, THE CAR MIGHT BUCK SLIGHTLY,THE ENGINE LIGHT COMES ON, & THE CAR STALLS. PRESSING THE GAS PEDAL HAS NO EFFECT; ALL I CAN DO IS COAST TO A STOP. SO FAR, I'VE BEEN LUCKY; I'VE BEEN ABLE TO COAST TO THE SHOULDER W/NO INCIDENT. USUALLY AFTER A COUPLE MINUTES, I CAN START THE CAR AGAIN,BUT THIS PAST SATURDAY, I WAS STRANDED FOR OVER AN HOUR BEFORE THE CAR WOULD START. THE PROBLEM HAPPENS IRREGULARLY, USUALLY WHEN IT'S WARM OUTSIDE. THE IDLE ALSO REVS ON ITS OWN; WHENEVER I TAKE MY FOOT OFF THE GAS & THE SPEED DROPS BELOW 30 MPH, IT REVS & JUMPS FORWARD UNLESS I IMMEDIATELY HIT THE BRAKES -- VERY DANGEROUS WHEN I'M HEADING TOWARDS A STOPLIGHT! THE CAR HAS HAD BOTH ITS IGNITION COIL & FUEL INJECTORS REPLACED, AND ALL BELTS ARE NEW; ALL MAINTENANCE IS KEPT UP, & THERE ARE NO OTHER PROBLEMS WITH THE CAR THAT WOULD CAUSE EITHER OF THESE ISSUES. AFTER DRIVING OUR MECHANIC & US NUTS FOR SEVERAL MONTHS, WE FINALLY FOUND OUT THAT THE PROBLEMS WERE DUE TO SHORTS CAUSED BY BAD INSULATIVE SPRAY ON THE ECU/COMPUTER CIRCUIT BOARD (THE ORIGINAL FACTORY INSTALLED UNIT), & WE ALSO FOUND OUT THAT WE WEREN'T ALONE IN HAVING THESE PROBLEMS -- THAT OTHER STORM & ISUZU OWNERS WERE HAVING THE SAME TROUBLE. THE FAULTY ECU IS WHAT GM/ISUZU REFUSE TO RECOGNIZE. ISUZU CLAIMS THE PROBLEMS ARE "NORMAL" -- I'VE YET TO DRIVE ANY CAR WHERE STALLING & DYING AT HIGH SPEED ON THE HIGHWAY IS CONSIDERED "NORMAL". *AK
