I have a 1994 Camaro Z-28 [owned since birth] with approx 80000 miles. It appears to be running rich as evidenced by the heavy soot in the tail pipes. Can anyone tell me where I can find a database that holds the most recent computer chip for this autopmobile? I am not looking to hot rod this car [it already has a lot of ZIP] only something that might correct some flaws in the original chip. The output from the car's computer does not identify any problem.
Thanks in advance
