So I have a 1992 mitsu eclipse GSX that seems to be running like total dog $hit. I have read over the codes I'm throwing and I've come up with 11 (O2 sensor, which I have a wideband in now), 12 (air flow sensor), 13 (air temperature sensor). Now I do recall having an issue very similar in my very first 1g and I could never get it figured out. It just seems to me that these MAF systems are super finicky in the 1g's, and I would like to know if anyone else has had these same problems.

Mass airflow has been changed twice
Still same codes
Still same running condition (runs rich as all h@ll with a definite miss fire.
The car does have a greddy E-manage Blue piggy back ECU in it as well if that raises any red flags.
