I'm not sure. All that happens in the PCM when the MAF is unplugged is the PCM resorts to the VE table. Which is pretty close to the MAF as far as fueling goes.


If your thinking that the MAF is bad then that's not the case. I have never heard of the MAF going bad and throwing a lean code. Like I said the most common symptom of a lean condition code is a vacume leak on these cars.



Although I guess anything is possbile.
