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.
