Default cars not working

car is stubling in low rpms and then stalls when slowing down for a light..This only happens once and awhile. I scanned the ecm,,,,,no codes showing up. When the car stalls, its at average temp.I just bought the car a realized that there was no coolent in the tank. Even with no coolent in the tank before, It did not overheat. I also noticed when sitting the car gets hotter (110o C/230oF) Is this normal? In the past few days when the car started stalling I have been getting worse and worse gas milage, any ideas? Also when the car stalls it take a while before in will crank over and stay alive.

Sounds like it could possibly be the Throttle position sensor (TPS) if it is a c4 that is.. :)

im not to familiar with the lt1 motor, but 230 does not seem unreasonable.. chances are the fan does not kick on until somewhere in that area.. my car the fan does not come on until 227degrees..

WoW!! No coolant! Not trying to be an a** but didn't you check the car out before you bought it. It sounds like the previous owner took p***poor
care of the car. I'd take it straight to the dealer for a good going over.

I agree Todd, you're pretty stupid for not checking the fluid levels prior to your purchase, but at 17 years old I don't blame your ignorance ;).

Seriously though, I think it's the opti as well.
