1991 GEO STORM Complaints

IDLE BECOMES ROUGH, BOUNCES AND DIES, FAILS TO START OR STARTS AND CHECK ENGINE LIGHT IS ON, RUNS VERY BAD. ONCE CAR SITS FOR A WHILE, STARTS TO RUN FINE, DOES IT WHEN IT IS WARM OUT. *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

I WAS COMING DOWN A 2 LANE AND IT JUST STOPPED AND GOT REAR ENDED WHEN IT SHUT OFF IT WAS THE ECM SHORTED BECAUSE OF SEALANT FROM FACTORY. *AK

FOR THE LAST 4YRS. I HAVE HAD TROUBLE AT START-UP,IDLE,DRIVABILITY OF THE ENGINE. ALL SENSORS RELATED TO THE IGNITION HAD BEEN CHECKED OR REPLACED. NOW ON 12/1/01 THE ALTERNATOR OVER CHARGED THE ELECTRICAL SYSTEM CAUSING A COMPLETE BURN-UP OF THE ECM,MAIN CIRCUIT PANEL AND SOME OF THE WIRING HARNESS. NEITHER THE 50AMP MAIN FUSE OR THE 30AMP ECM FUSE BLEW (LIKE THEY SHOULD HAVE) STOPPING THE 160 AMPS FROM THE ALTERNATOR. *AK

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

I SENT ONE COMPLAINT TODAY, WITH SOME ERRORS. I AM SENDING THIS COMPLAINT TO CORRECT THESE ERRORS, AND ALSO TO COMPLAIN A LITTLE MORE. I CAN BARELEY MAKE IT TO SCHOOL IN MY CAR WITHOUT WORRING IF IT IS GOING TO DIE OR NOT. SEVERAL TIMES IT HAS DIED IN THE MIDDLE OF BUSY INTERSECTIONS NOT ONLY PUTTING MYSELF IN DANGER, BUT ALSO THE OTHER MOTRISTS AROUND ME. I AM A YOUNG KID ON A TIGHT BUDGET AND WOULD LIKE TO SEE SOMETHING DONE ABOUT THIS. THANK YOU. *AK

THE SYMPTOMS OF THIS FAULT ARE MOST NOTABLY ERRATIC IDLE, IDLE REVVING AND DROPPING. *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
