1992 Geo Storm electrical problems

Filed Nov 18, 2003 · Electrical · 131,680 miles · PA

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.

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.....

Ecu causing erratic idle in my 1992 geo storm. It is worse in warm weather. It has almost caused me to run into a train when r.p.m jumped up to over 2000 RPM. Since it was an automatic it lurched forward. Gm said it was because of insulating spray contracting causing shorts in ecu. My car has shut off in traffic causing traffic jams also. Please make gm recall these cars for ecu repair before some one gets killed.

For well over a year now, my 1992 geo storm-4 cyl., has exhibited RPM's above 2000 when idling at a stop when the ambient temperature is above 60 degrees f. I must keep the brake pedal firmly pressed to the floor since the auto. Transmission wants to engage. This symptom also causes my vehicle to act as if it is engaged in cruise control, accelerating to about 30 MPH, once the brake pedal is released. Cruise control was not option installed in the car at purchase. I have come to realize this is also a problem with isuzu's, (the geo storm engine is an isuzu product), all due to the failure of the insulative spray on the ECM. I certainly hope the manufacturers can be held responsible for fixing this potentially dangerous condition.

Rpms rev up and down... Car dies... Insulative spray that manufacturer uses on the computer shinks and contracts with changing temperatures and breaks the solder at the computer causing misfires at idle and thoughout all driving speeds and ranges, engine revving up and down, engine dying, and RPM holding at 2000 RPM gm knows about the fault in there computers...they refuse to fix it at their expense... They used this spray on insulators on 85-93 delco computers... They use a new spray on 95 and up, but don't on factory reconditionerd ecu's prior to 1995.

The faulty ecu component on my car has again made my car to stall, but this time I was in a bad situation, w/the engine stalling out I had no power steering and power brakes, thus causing me to drive into a 10ft deep ditch. As metioned before, this has not been the only time my car has stalled due to this problem (ie in the middle of busy intersections and so forth) this is a very dagerous defect that, izuzu uand the federal safety agency are aware of, I'm hoping that this incident along w/the many others is enough for the federal safety agency to correct the problem . Thank you.

I apologize if some of my data entry seems illogical. My ECM was bad since the first day I purchased my used geo storm gsi. I had every erratic idle/driveability problem possible. When pulling up to lights the car would idle at 3000 rpms. In traffic, t.

This ecu has been the culrpit in an idle problem. Car will die at take off, and has this has been th second time replacing one.

Many people I know have this same computer problem. Please help us fix this. Thank you.

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.
