    Replaced maf and no change.

    I have been having problems with rough idle and at times the car would not accelerate from a stop. MAF was replaced and I still had the problem yesterday. Funny thing is when I have the problem in the morning it seems to fix itself and the check engine light goes off and car drives great. Other times the cel is always on but it seems to drive fine but a little sluggish at times. This morning I went out to start the car and it wanted to die until I got it warmed up. Every time I would let it idle the cel came on but when I pushed the gas it would go off again. Error codes from stomp test show 1213. Ideas?

    Get all the oil out of your spark plug wells first. Code 1213 is the only thing OBD I will ever tell you. ALL IT MEANS is that you are running too rich or too lean for 10 seconds or more. It does NOT mean your O2 sensors are bad.
