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.

What 1991 Geo Storm owners say
Most recent owner complaints, unedited.
This is the 2nd ECM control module in 2 years. . .both were new with only a year warranty. . .problem only shows up in the summer.
General motors used a shrinking sealant on the computer boards in these cars which they have since quite using and admit it was a problem, but still use it on the replacement parts when this shrinks it pulls the components on board loose, causing poor idle/ hesitation and stalling even during acceleration (ie when pulling out in traffic).
No summary listed for above vehicle.
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.
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.
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.
Car has erratic idle at times and rpms will stick sometimes well above normal idle. It is ecu that is causing the problem. Quite a few of my friends experience this problem with the geo storms. A recall is in order if you ask me!
The ECM died, and according to a survey, a lot of other peoples have also, recall it!
Car loses power with no indication of a problem. All speeds. Been chasing problem for almost 3 years now.
