The car...92 Vette 383 stroker. 10k on new engine. Nothing done to it for at least the last 6k miles other than a PCM tune that i got from PCMforless about 3k miles ago.

All of a sudden today when i left to run to the store my vette told me it didn't want to stay running.

1. The engine will stay running if i have it revved up to 1k, but if i try to let it idle itself it just stalls. While it is still running at 1k the exhaust is rich as hell.

2. The Service Engine soon light is on, and i just went to buy a code reader and i hooked it up and the light isn't blinking. I don't think it's operator error. Does PCMforless take the ability to read codes out? I know the tuner i work with on my turbo buick can mess with some stuff and you lose that ability.

3. The "Service ASR" light is on.

4. The volts look normal, but when i look at coolant temp it says "sys low". It shouldn't be low, i haven't been running hot since i cleaned out the radator and at that time it was full.

5. The fuel injectors seem kind of loud, but that might just be because i never paid attention before. The are bigger than stock injectors.

 

i kinda had the same problem and i found out that it was a blown head gasket so u might want to have that checked out.
