Replaced MAF sensor and MAF relays, replaced O2 sensor, did a plug, cap, rotor, wire tune up, still running rich. Don't really know where else to look besides the ECM. Any ideas? Need to pass inspection

 

Check for high fuel pressure or fast bleed down rate.

 

Is there a check engine light? EGR can make a car run rich as well as an o2 sensor. so can a vacuum leak. Since it's a maf car, any vac leak after the maf sensor is unmetered air going into the motor, the ecm picks up on this lean condition and starts adding more fuel to compensate for the extra air causing it to run rich.
