1993 Geo Storm: engine stalls while driving

Filed May 15, 2003 · Electrical · 130,000 miles · PA

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.

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

Car is stalling and cutting out and leaving me stranded, will not start up again until car cools down. The are no trouble codes found by the dealer or other mechanics but there is a serious problem. Car loses power and the RPM jump up and then dropped back down and the check engine light flashes on and off. Car has stalled while driving on the interstate (at 65 MPH) and the check engine light flashes on and back off. The dealer keeps telling me they can't find anything wrong when obviously there is a problem.

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.

My family and myself were left stranded, when my car just stalled in the middle of the road, 40 miles from our house. I have read numerous reports about accidents that have been caused by this "mysterious" problem. Luckily for me, there were citizens who rushed to my aid to help push my car out of traffic. I have a 5 year old daughter who needs to get enrolled in school, I have no means of transportation as of this time, what am I to do??? I've been a united states marine for the past 4 years now and I'm ready and willing to defend you if the need presents itself, yet, you can't complete an investigation of a well known defect and fix my car??? I have replaced everything I can think of and after a $100 towing bill, my car is now at the dealership and who knows how much this is gonna cost me and my family. Please help all of us who are out there with this problem, I can't afford another car....I need some help.

I have had several problems with the vehicles RPM's reving iradically. I have also had the vehicle shut off on me while I was driving down the freeway. I was lucky I did not wreak. A car stalling on the freeway is no fun. When I stalled the lights and everything shut down. I couldn't even put on my flashers.

The vehicle kept stalling out and making loud noise when accelerator was applied.also, exhaust fumes were entering into passenger's compartment. This was due to a cracked manifold. Dealer has vehicle currently.
