I have a 1999 Explorer with 200000 + miles on it. I just had the head gasket and heads replaced. The check engine light was still on and the idol was rough, had the codes read, stated bank 1 & 2 were running too lean. I changed the mass air flow sensor. It fixed the rough idol but now it won't stay running while at a light and when I am driving steady, it will stick as if it's not getting enough gas and then jump and go. I had the codes read again, and now they say bank 1 & 2 run too rich. I changed the throttle position sensor as well. I am at a total loss and just can't afford to keep taking guesses. Does anyone have any idea what the problem may be?
