Hello all
I have a 1993 LT1 that is giving me a problem similar to what Fifty8bowty
is seeing on his. It runs great and then will just turn off. I pull over and wait a moment and it then starts right back up. I am a mostly a Harley mechanic but have some car expirence under my belt. Not sure where to start and looking for some assistance as it is a bit frustrating. HELP!!!

I also see that I have the selection (green) indicator light on the climate control blinking and today when it shut off the LCD for the climate control went to a dash and line _ _____
and nothing worked. I turned the car off and re-started it and was back to a normal readout but still had the flashing light. I was looking back at some of the suggestions in this thread and I am going to try and locate the bundle of grounds and make sure they are all making good contact. Could the shuting off and the climate control be related?

So what's the verdict Fifty8bowty? Did you resolve the code 36 issue?

I'm experiencing a similar issue, that is getting a code 36. Prior to this error setting, I experienced some odd drivability issues. While driving in rain I noticed the vette was in a constant state of stalling with an enormous reduction of power. The next day it was fine. My thoughts are a defective Opti. But now I'm wondering if it's a loose ground connection or deteriorated wire insulators.
This forum is invaluable.
