94 should still be OBD-1, which means you can read trouble codes with a paperclip. Do a google search, there are a number of sites that'll tell you how to read the codes & what they mean.

On a Chevy, basically you short two terminals in the OBD connector under the dash with a paperclip, turn the key to the run position but don't start the engine, and count the flashes on the check engine light. OBD-1 Fords have a similar procedure but use voltage pulses out of an underhood diagnostic connector instead of flashing the check engine light.

Good luck. I seem to remember that there are a few things that'll cause it to run rich or go into limp-home mode but won't set a trouble code, but its been long enough since I owned an OBD-I Chevy that I don't remember the details.

PS...Haynes, Chiltons, etc. will have the diagnostic codes in their repair manuals also. Most libraries have them.
