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
THE E.C.U. IS BAD IN MY 1991 GEO STORM 2+2. IT IS A COMMON PROBLEM WITH THESE CARS AND GM WILL NOT DO ANYTHING ABOUT IT. *LA
THE VEHICLE STALLED WITHOUT WARNING. THE DEALER REPLACED THE DISTRIBUTOR CAP, SPARK PLUG WIRES AND ROTOR, HOWEVER THE PROBLEM RECURRED. *JB
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

295V103007 · Seat Belts:front:buckle Assembly
May 24, 1995
THE FRONT SAFETY BELT BUCKLE RELEASE BUTTONS CAN BREAK. THESE RED PLASTIC RELEASE BUTTONS ARE MARKED "PRESS." IF A BUTTON BREAKS, PIECES CAN FALL INTO THE BUCKLE ASSEMBLY CAUSING THE BUCKLE TO OPERATE IMPROPERLY.
Consequence & remedy
Consequence: THE SAFETY BELTS WOULD NOT PROVIDE ADEQUATE PROTECTION TO AN OCCUPANT IN A VEHICLE CRASH.
Remedy: OWNERS SHOULD PROMPTLY CHECK THE CONDITION AND OPERATION OF BOTH FRONT SAFETY BELT BUCKLES AND CAREFULLY INSPECT THE RED RELEASE BUTTON FOR ANY BREAKS OR CRACKS. THEY SHOULD ENSURE THAT BOTH BUCKLES ARE OPERATING PROPERLY BY INSERTING EACH LATCH PLATE INTO ITS BUCKLE, TUGGING ON THE BELT TO MAKE SURE THE LATCH IS SECURELY LOCKED, AND THEN PRESSING THE RELEASE BUTTON. THE LATCH PLATE SHOULD POP OUT OF THE BUCKLE WHEN THE BUTTON IS PRESSED. IF EITHER RELEASE BUTTON SHOWS A SIGN OF BREAKING OR CRACKING OR IF EITHER BUCKLE FAILS TO OPERATE PROPERLY, OWNERS SHOULD PROMPTLY CONTACT THEIR AUTHORIZED DEALER TO SCHEDULE AN APPOINTMENT TO HAVE THE BUCKLE REPLACED OR REPAIRED, FREE OF CHARGE. THE MANUFACTURER IS DEVELOPING A REMEDY DESIGNED TO PREVENT FAILURE OF THE BUTTONS THAT ARE NOT CURRENTLY BROKEN.
