Then how do you reset the computer? Just did heads, cam, rockers, need computer to relearn.

If you have the PCM "out", do you have all the harness plugs disconnected? If so, it has no power, and the volatile memory (long term fuel corrections, learned idle position and stored trouble codes) have been cleared. Nothing else to do.

If the harness connectors are still connected, you need to pull the "PCM BAT" fuse for 30-seconds. Its not in the PCM. That fuse is either in the panel at the end of the dash (93/94) or in the underhood box (95 and newer).

If you did any sort of serious heads/cam, it needs more than to "relearn"... it needs a reprogramming.
