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
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
Try a running fuel pressure test, then a standing fuel pressure test.
If the running fuel pressure test is low, there's your problem. Fuel pump or
regulator. Standing fuel pressure test will eliminate this:
Any pressure loss in an hour or so, means a leaking injector or pressure
regulator. Start it and get the pressure back up, shut it and pinch off the
return line. Any pressure loss means a leaky injector.
I hope this helps?
