The car has trouble in the mornings or at cold starts. It starts fine everytime but after it idles down a bit the car starts to run rough. This will continue as i start to accelerate, its chuggs as i get up to speed. but as i get to 40 or 50 mph the chugging quits and the car runs fine. I replaced the plugs, wires, coil pack, IAC and cleaned the MAF. No luck. The codes say its running rich and another one that says Manufacturer Control Fuel Air Metering. Any ideas for what can be causing this?
