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. *Tr
Ecm causes engine rpm to increase during warm/hot weather which will not drop to normal when the clutch is engaged unless the throttle is physically moved (blipped). This dangerous as it doesn't always happen and can cause the car to not decelerate when the throttle pedal is lifted. This is not a once a year defect as you ask below; (had to fill in the blocks or I couldn't continue). It is prevalent on all fwd isuzu built automobiles from 1989 through 1994. *La

On sunday, october 13, 2002 my husband was taking our 3 children home and he had only got 1/2 mile from the house and going down the road at 55mph the car just cut off. Leaving my husband and 15 year old son just sitting in the middle of the road. The car would not restart, and thank god there was no-one behind him. No lights or warnings came on and the car would not move. They were stranded for 4 hours in the road. Thank god they had not made it to the 4 lane highway that they were headed for or crossing a...

busy intersection. I just know that god had to be with them. They were able to finally push the car off the middle of the road. After getting someone to pick my husband up and bring him home, he and a neighbor went back to see if they could find out what was wrong with the car. After replacing everything that they could, and nothing helped, we called a wreaker to take the car in. It had to be put on a flat bed to be taken in. It was taken to a gargage. Where after putting it on a machine and checking the ecus/computer it was found it had failed. Now after 4 days we are still not able to find a new computer board to be put in the car, not even through the dealer because no-one knows how to program the boards. So, after calling several places they were able to find a used one in north carolina which is being sent down by truck. Still not knowing if this is going to work, however the worst part is, if this is a used one when will it go out? And, where will it happen, with no warning and going any speed it will just stop, go dead and not restart..... I really belive something should be done about this before if not already innocent people die. Or children get killed. Just think if you were going down a 6 lane highway and anywhere from 55-70 and the car just stop and cars all around you and behind you. And, the car not start back up or even get a chance to get the car started before some one runs into you and kills you, them, and anyone else around...

Engine control computer improperly built causing erractic idle from 2000rpm to 500rpm, car stalls and will not start. Isuzu has been contacted about this and has stated"we do not make cars" and they fail to rectify the problem. There are very many of us who would like to see this issue resolved as our cars stalling in traffic and idling erractically is causing a lot of problems as in poor efficiency and unneeded downtime. The problem is in the insulative spray on the main circuit bopar dof the units that breaks...
