The median odometer reading at the time of complaint was 40,000 miles.
In owners' own words
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. Electrical system
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). Electrical system
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. Electrical system · reported at 86,000 miles
