E engine code (TBI) is 6 degrees BTDC for both the automatic and the manual trans I'm pretty sure the F engine code is the same (TPI). Of course any sticker under the hood that says otherwise overrides what I just said here. The way to tell whether you have the E or F engine code is; The E engine code is Throttle Body injected, and the Throttle Body injector will look a lot like a carburator. If it is F engine code, Tuned Port Fuel Injected, the throttle body will be very small and on the front of the intake plenum, there will also be 8 tubes going from the intake plenum to the intake manifold. If you can't identify these components please take it to a qualified mechanic.
try adjusting the ignition timing(or getting a mechanic to do it)
Manual states...15.5 gal
The timing for this engine is electronically controlled and not adjustable
6 BTDC
try autozone.com
Bring it to a shop and have them adjust the timing with a timing gun I believe its 6*
The timing on that year engine is computer controlled. It requires an engine scanner to set the timing. YOU CAN NOT USE A TIMING LIGHT.
there was no 350 in the camaros in 83 just 305 and v6

cam timing will not change ignition timing i would try 8 or 10 degees advance at idle with the vacuum advance disconnected.
