My 1992 LT1 Coupe has developed electronic problems. I thought I posted this subject before, but cannot find it anyplace within the site. Here it goes again.
At ambient temperatures above 60 degress F. the following occurs:
1. There is a surge felt in the rear end.
2. The engine idle RPM goes to 1500-2000 RPM.
3. The service engine soon light illuminates.
4. The service ASR light illuminates.
5. The digital speedometer display goes to zero.
6. The air conditioning goes to heat.
7. The engine RPM will occasionally fluctuate violently and be considerably unstable. There
is no power when attempting to accelerate and
all one can do is allow the engine idle RPM to move the vehicle along.
8. The engine stalls when the car is stopped in traffic. It will restart normally but the symtoms reappear.
9. Occasionally while driving, the symtoms disappear for a time then reappear and then may disappear again. The warmer the ambient temperature is the longer the symtoms last.
10. At temperatures above 75 degrees F. the symtoms appear and do not disappear at all.
At ambient temperatures below 55 degrees F. items 1, 2,7 and 8 occur.
At ambient temperatures below 45 degrees F. the car operates perfectly with no symtoms.
The dealer could not repeat the symtoms and indicated the problem was in the body control module. They said that they would need the car for 2 days to dismantle the dash and console to locate the BCM and do analyticals to isolate the cause. There would be no guarantee. before I head down that road, I would like to attempt the repair myself as I just know that the dealer tech will never reassemble the dash and console correctly to look as if it had never been touched. I would like to know if there is anyone out there who knows what the cause of the problem is and what corrective action to take. Also, if anyone knows a quality repair shop in the Stratford, Connecticut area, please advise. Please respond to my e-mail address which is DaveSuhy@SNET.net.
