1990 GEO STORM Electrical Systemignitionmodule Problems

SOME ONE SHOULD FIX THE PROBLEM SO I CAN BUY A NEW ECM. *AK

PROBLEM WITH THE ECU IS A GMC MANUFACTURING DEFECT. DEALER WILL NOT REPLACE ECU. ECU HAS PROBLEM WITH BOARD LAMINATE EXPANDING AND CONTRACTING WITH TEMPERATURE CHANGE WHICH CAUSES DAMAGE TO THE CIRCUIT BOARD AND CHIP CONNECTIONS. SHOULD BE RECALLED AND REPLACED BY GM FREE OF CHARGE FOR ALL GEO STORMS. EXHAUST HEADER IS MADE OF IRON AND RUSTS IMMEDIATELY AFTER INSTALLATION. A FEW YEARS AFTERWARDS, EXHAUST HEADER WILL CRACK AND MUST BE REPLACED AT OWNER'S COST. THIS PART SHOULD BE REPLACED BY DEALER WITH SAME PART, FREE OF CHARGE, EVERY TIME IT BREAKS, OR REPLACED WITH A COMPONENT THAT WILL NOT RUST AND CRACK. *AK

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. *AK

ECM FAILURE BEGAN SLIGHTLY AFTER I PURCHASED THE CAR WITH 80000 MILES ON IT. ENGINE WOULD RUN, THEN SHUT DOWN FOR NO APPARENT REASON, WHICH COULD BE A SEVERE HAZARD. MECHANIC IDENTIFIED PROBLEM, AND DEALERSHIP REPORTED THEY HAD SEEN MANY STORMS WITH THE SAME PROBLEM. SINCE THEN I HAVE SPOKEN TO 20 OR 30 OTHER STORM OWNERS WHOS CARS DEVELOPED SIMIALR PROBLEMS AFTER 3 YEARS OR 80000 MILES DEPENDING ON HOW CAR WAS DRIVEN. WOULD ALSO LIKE TO RECIEVE FURTHER CORRESPONDANCE ON ABILITY TO HAVE CAR RECALLED ON SUCH PREMISES. *AK
