Re: 1994.5 can you use a scan tool or a tuner ?
If the PCM
was reflashed by the dealer, the diagnostic port under the dash should now be active. 94's came from the factory with that port inactive (you had to do diagnostics , which were very limited, using the port located in the engine compartment). Cheers!
