What owners say
7 months and 5 replacement ecus on my 1991 geo storm gsi, and still has dangerous issues of stalling on highway and when pulling out into traffic. The problem is that between 1985 and 1995, 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. Gm knows about this fault in their AC delco ecus/computers and has even gone so far as to include supplemental instructions on how to test for shorts and broken circuits in the ecu/computer to their technical literature, though they refuse to repair or replace the problem at their own expense. Gm went further and began using a different insulative spray on all of their ecus/computers in 1996, though they do not use this new spray on their factory reconditioned ecus/computers for the geo storm models.
1992 geo storm manual transmission. When engine gets hot ( summer months ) engine idle increases to 2,500 - 3,500 RPM. Must use foot to pull up on accelarator. Car begins to overheat lurches forward. Car also stalls without warning. Heard it has to do with faulty ECM. Very dangerous situation.
Driver noticed that the vehicle hesitated and slowed down on its own. Transmission light flashed on then off. Driver pulled over, and the vehicle stalled. Driver was unable to restart the vehicle, and it was towed to a mechanic shop, and mechanic determined that transmission needed to be replaced.
I have a 1992 geo storm 2+2 with a 12 valve motor and a 5 speed manual transmission the car constantly overheats even after entire cooling system was replace. Car stalls, idles eratically due to gm's faulty ECM insulative spray. And just recently loss of rear tail lamps and dash lamps. Brake turning and hazard lamps still work. All fuses and relays are good.
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.
Car idles erratically, it also idles above 2000 RPM sometimes it lacks power and sometime it does not. The car stalls while at idle, or sometimes it pumps gas irregularly causing a pulsing.....
The vehicle stalled without warning. The dealer replaced the distributor cap, spark plug wires and rotor, however the problem recurred.
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.
