1991 GEO STORM Complaints

CAR HAS ERRATIC IDLE AT TIMES AND RPMS WILL STICK SOMETIMES WELL ABOVE NORMAL IDLE. IT IS ECU THAT IS CAUSING THE PROBLEM. QUITE A FEW OF MY FRIENDS EXPERIENCE THIS PROBLEM WITH THE GEO STORMS. A RECALL IS IN ORDER IF YOU ASK ME!*AK

THE ECM DIED, AND ACCORDING TO A SURVEY, A LOT OF OTHER PEOPLES HAVE ALSO, RECALL IT! *AK

CAR LOSES POWER WITH NO INDICATION OF A PROBLEM. ALL SPEEDS. BEEN CHASING PROBLEM FOR ALMOST 3 YEARS NOW. *AK

THIS ECU PROBLEM IS VERY UNSAFE! IT CAUSES THE VEHICLE TO SURGE AT INTERSECTIONS WHEN BRAKING OR FAIL TO STAY RUNNING IN TAFFIC. THE ECU ALSO CAUSES THE VEHICLE TO SPUTTER AND CUT-OUT AT HI-WAY SPEEDS, CAUSING THE VEHICLE TO SUDDENLY SLOW DOWN IN TRAFFIC.*AK

FAULTY ECM CAUSES ERRATIC IDLE SPEEDS. AFTER STARTING, ENGINE RPMS DROP AND ENGINE MAY STALL WITHIN 30 SECONDS EVERY TIME ENGINE IS STARTED. WHILE STOPPED AT LIGHTS OR IDLING, ENGINE WILL OFTEN STALL OUT. ENGINE WILL ALSO OFTEN REV TO OVER 2,000 RPMS. THIS HAS CAUSED VEHICLE TO STRIKE THE REAR OF ANOTHER VEHICLE AT A STOP. THIS PROBLEM REPORTEDLY OCCURS DUE TO MALFUNCTION IN ECU DUE TO SHRINKAGE OF THE INSULATION USED ON IT.

EXPERIENCING PROBLEM WITH VEHICLE STARTING ITSELF AND ENGAGING OUT OF OUT OF GEAR ( W/O KEY AND VEHICLE WOULD BE COMPLETELY OFF). CONDITION HAVE OCCUR ON FOUR OCCASION WITHIN A WEEK. VEHICLE WILL BE TAKEN TO THE DEALER FOR INSEPECTION. PLEASE PROVIDE ANY FURTHER DETAILS.

GM & ISUZU ARE AWARE OF THIS. APPARENTLY THEY HAVE REFUSED TO FIX IT. MY CAR HAS JUST BEGUN THESE SYMPTOMS BUT I DON'T WANT TO WAIT UNTIL THE CAR DIES ON ME. THIS YEAR WE HAVE HAD RECORD HIGHS IN CA. IT'S MAKING THE PROBLEM WORSE. IT CUTS OFF WHEN IT FEELS LIKE IT FOR NO GOOD REASON. IT IDLES HIGH AND LOW. IT HAS EVE REFUSED TO START AT TIMES.*AK

THIS IS KNOWN TO BE AN ENDEMIC PROBLEM WITH THIS VEHICLE AND RELATED ISUZU VEHICLES. THE ITEM WAS INHERENTLY DEFECTIVE AND CREATES A SAFETY HAZARD WHEN IT FLARES UP, CAUSING THE CAR TO MALFUNCTION AND OVERHEAT WITHOUT WARNING.NO SAFETY DEFECT LISTED. *AK

EXHAUST MANIFOLD CRACKED, CAUSING VEHICLE TO STALL. EXHAUST ODOR COMING THROUGH FRONT OF CAR. *AK

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. *AK
