Even though you cleaned the mass air flow sensor, that won't help if it has gone bad. Try replacing it and see how it does. They tend to go bad on Ford vehicles a lot.

Would a MAF Sensor failure make the check engine light come on? If so, it has not shown up in the computer. THX

Yes, that would definately make the check engine light come on. I have a 5.0 Mustang and my MAF was bad and the code reader just read "error".

The check engine light is on now, and the codes are for the o2 sensor I replaced and air/fuel metering. My tech manual doesn't say anything on the subject of metering. Nothing about MAF Sensor.

If the code says O2 sensor, try replacing them and see how it does. If they are bad, they'll throw off the air/fuel mixture which will make the car run rough.

I replaced the one that the comp. said was bad, but at $80.00 each I didnt want to go broke either. The metering code didnt come in till after I had replaced the bad one.

So, did you get the trouble code for the sensor after you replaced it? If so, that doesn't make any sense to me. Which sensor and bank did you replace? Yes, I know they're expensive, I have a Mustang with the 4.6 and had to replace two of them.

Thx for all of your help but I traded the car in. Let someone else figure it out!? I was also told that the brain was probably getting ready to go!!
