TAC module After doing some research, it appears that the 1518 code is related to the TAC module...isn't that only used for DBW throttle bodies? I am using a cable driven (non-electronic) t-body.
Could my PCM be programmed for a DBW setup? Could this be why the engine bogs down and won't rev?

If you have a cable setup, and a DBW program, the PCM is not getting a TPS signal. Thus no accel enrichment. That = lean/knock possibilities.
B4 I went further, I'd take a look at the PCM w/ a tuner. [IE: EfiLive]
PS: Just looked at my EFILIVE.. I see 15 PIDS referring to the DBW.
