1991 GEO STORM Engine And Engine Coolingenginegasoline Problems

ONGOING PROBLEM WITH ENGINE STALLING / CUTTING OFF WHILE DRIVING AT MULTIPLE SPEED. VEHICLE BEEN TO DEALER, BUT PROBLEM REOCCURRING. FEEL FREE TO PROVIDE ANY FURTHER INFORMATION.*AK

ENGINE CONTROL COMPUTER IMPROPERLY BUILT CAUSING ERRACTIC IDLE FROM 2000RPM TO 500RPM, CAR STALLS AND WILL NOT START. ISUZU HAS BEEN CONTACTED ABOUT THIS AND HAS STATED"WE DO NOT MAKE CARS" AND THEY FAIL TO RECTIFY THE PROBLEM. THERE ARE VERY MANY OF US WHO WOULD LIKE TO SEE THIS ISSUE RESOLVED AS OUR CARS STALLING IN TRAFFIC AND IDLING ERRACTICALLY IS CAUSING A LOT OF PROBLEMS AS IN POOR EFFICIENCY AND UNNEEDED DOWNTIME. THE PROBLEM IS IN THE INSULATIVE SPRAY ON THE MAIN CIRCUIT BOPAR DOF THE UNITS THAT BREAKS DOWN OVER TIME DUE TO HEAT AND EXTREME(HOT OR COLD) TEMPS. GMC HAS RECOGNIZED THIS PROBLEM AND FAILS TO DO ANYTHING ABOUT IT. WE WOULD LIKE THIS ISSUE ADDRESSED AND I SPEAK FOR THE OVER 500 MEMBERS OF THE GEO STORM OWNERS CLUB, WWW.STORMOWNERS.COM. *AK

WHEN I START THE CAR WITH THE ENGINE COLD, AS SOON AS THE CHOKE TURNS OFF, THE ENGINES DIES, I HAVE TO TAP THE ACCELERATOR TO KEEP THE ENGINE RUNNING. ONCE THE ENGINE IS OPERATING TEMPERATURE, I SHIFT THE TRANSAXLE INTO PARK, AND THE IDLE SHOOTS UP TO 2000 RPMS, THE ENGINE IDLES UP AND DOWN WHILE THE CAR IS IN PARK. THE IDLE ALSO DROP TEMPORARILY WHEN THE BRAKES ARE DEPRESSED THIS STARTED HAPPENING DURING THE LAST WEEK WHEN THE WEATHER TURNED HOT FOR THE SUMMER.*AK

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

FROM THE TIME THE VEHICLE WAS PURCHASED THE CAR HAS IDLED ERRATICALLY WHILE SITTING STILL, AND SOMETIMES WHEN IT WAS COLD. *AK

AT AN IDLE, IN PARK OR IN GEAR, THE ENGINE SPEED OFTEN RISES FROM NORMAL (1000RPM) UP TO AS HIGH AS 4000 RPMS. THIS HAPPENS AT A STAND STILL AND ALSO WHEN APPROACHING, SITTING AT OR LEAVING STOPP LIGHTS ALSO. THIS PROBLEM HAS CAUSED UNWANTED AND UNSAFE "LURCHEING" FORWARD WHEN LETTING OUT THE CLUTCH. AT TIMES, WHEN THE ENGINE SPEED COMES BACK DOWN, IT WILL DROP TOO FAR AND CAUSE THE ENGINE TO STALL. THIS HAPPENED TO ME IN THE MIDDLE OF A BUSY INTER SECTION AND I WAS NEARLY REARENDED. TO MY KNOWLEDGE GM IS AWARE OF THIS PROBLEM BUT REFUSES TO TAKE CARE OF IT OUTSIDE NORMAL WARRANTY PERIOD.*AK

ENGINE IDLES UNCONTROLABLY AT HIGH RPMS (2000+) WHEN STOPPED, THIS PRESENTS A SAFTEY THREAT IF I SHOULD HAVE MY FOOT SLIP OFF THE CLUTCH OR HAVE A CABLE FAILURE BECAUSE THE CAR WILL LURCH FORWARD BEFORE THE ENGINE DIES. THIS COULD CAUSE AN ACCIDENT INVOLVING A PEDESTRIAN OR TRAFFIC GOING THE OTHER DIRECTION AT AN INTERSECTION.

ERRATIC IDLE SPEED THAT REVS AND DROPS WHILE YOU ARE COASTING OR AFTER YOU COME TO A STOP. SOMETIMES IT REVS HIGH INTO THE RPM RANGE ABOVE IDLE SPEED, SOMETIMES IT DROPS SUCH THAT THE ENGINE NEARLY DIES OR DOES DIE. HOVERING IDLE SPEED THAT HANGS AT CRUISING LEVEL WHILE YOU ARE COASTING OR AFTER YOU HAVE COME TO A STOP, USUALLY 2,000-3,000 RPM. SOMETIMES, IF YOU WAIT A WHILE, IT COMES DOWN ON ITS OWN, SOMETIMES IT DOES NOT.HOVERING IDLE SPEED THAT HANGS AT CRUISING LEVEL WHILE YOU ARE COASTING OR AFTER YOU HAVE COME TO A STOP, USUALLY 2,000-3,000 RPM.
