Got a meter, they only had digital ones, and it is hard to read exactly what the code is, it goes through the numbers so fast. I think it's either the O2 sensor, or the MAS. I just had the O2 sensor changed a a dealership, so I think I might bring it back into them and see if the sensor they put in is bad. Any thoughts?

Really, there's a cheaper and MUCH easier way to find codes for 1st gens. Go to RadioShack and buy a cheap buzzer, I think they're like 99 cents or somethin. Anyways, you can tell for sure if it's a short or long easily.
