Take a paper clip or something similar to ground out the diognostic terminals & get whatever trouble codes are stored.
If you're not familliar how to do this, the OBD-I test terminal has three wires (at least GM does): two on one end and one on the other. You jump the two that are adjacent to each other. With the key ON, engine not running, Watch the SES idiot light flash like morse code. All codes are 2 digit numbers: two flashes followed by three flashes = code 23, and so-on. Each particular code sequence will flash three times, then go to the next. When all the stored codes are finished, it will start back at the beginning. Usually code 12 is the first one. That just means there are some codes stored. If it throws out two or three codes and then goes back to 12, you know it has cycled through everything. Just have a good pen and paper ready. I think you can Google the list of codes for whatever year/make/model and get the definitions. I suspect a throttle position switch could also be the culprit. What year Fiero? |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
