My 1993 geo storm has started stopping running while being driven and leaving me stranded. It is currently in the shop and appears to have a bad ECM. Sources on the internet indicate this is an inherent problem in the model car.

93 geo storm randomly stalls and will not restart for several minutes to several hours. Have replaced cap, wires, rotor, plugs, pick-up and ignition module and cannot find problem. I have found many reports of the insulation on the ecu going bad and causing problems.

My 1993 geo storm has been stalling lately. It is totally sporadic and does it when I am pulling out, when it is idling, and when I am on a freeway going along at a constant speed. This has put me in a very serious situation a number of times and has severely shaken me. It will stall in the middle of an intersection, and luckily all 6 times this happened no one was coming either way. I no longer drive my car, and I am afraid to sell it due to the fact this will happen to someone else. I had checked everything I could think of until I read a article about the electronic control module being bad in 89-93 geo storms, isuzu impulses, and asuna sunfires. I would like to see a major recall put forth to fix this problem. Thank you.

The car started fine after that. Four days later, after a 45 min. Dentist apppointment, my car would not start. After 15 minutes of troubleshooting, it suddenly started. I have been encountering these same problems ever since.

Vehicle will stall while driving. Consumer believes there is a fault in ecu. Consumer is very concerned about safety while driving.

This car has had a habit of stalling while goin down the road, at any speed( once while in a six lane highway, crossing the merrimack river, in st. Louis, mo. I have had it to lee kinstle chevrolet/gm, van wert, oh, winkle chevrolet, paulding, oh, and a chevrolet/geo dealer, in balwin, mo. I can't remember the name. I have had a complete tune-up, including plugs, rotor. Cap, and plug wires. I had all the wiring gone over twice. A new fuel pump, twice, and it still stops at any moment. I am afraid someone will be in a crash, due to loss of power steering, and power brakes. Can you help? I don't know where to turn!!

The ecu seems to have failed, it is a known problem with this car. I was driving through town and came to a stop light, idle stayed at 2000rpm, normal idle is 800-1000. Kept driving. On way home from errands car stalled once at a light, tried to stall several other times (all while idling) with enging RPM dipping as low as 500 (or 0rpm when it stalled). Following is a link to an article about the problem. Http://www.isuzuperformance.com/isuzuweb/recall.html ---- (all cars listed in that report are sister cars, with drivetrains built by isuzu) I have experienced the problems listed there, except for the car going on its own, as my car is a manual. Thank you for your time in this regard. The exhaust manifold problem has been known to gm and isuzu for a long time know, with virtually every storm and stylus on the road having cracked their original exhaust manifold. This problem is obviously dangerous, as it allows noxious exhaust fumes to enter the atmosphere and engine compartment, bypassing the catalytic converter. Once again, thank you for your time.

I've had the electronic control module replaced three times with a rebuilt one in the last year by auburn chevrolet of auburn, wa. This is an intermittent problem where the rpms change up and down on there own and the engine usually shuts down. No fault indications are displayed. It seems to happen more often with changing temperatures. I almost got in an accident twice, once on the freeway and once in an intersection.
