Im having an issue where sometimes during cold start the CEL will instantly be one and I will have a rough idle. The CEL will stay on until the car is warm, then go off after driving for about 1 mile. Once I come to a stop, it will intermittently come on with no symptoms and a rock solid idle, and will then go off as soon as I start rolling. When I press the throttle while the CEL is on I can feel a vibration through the pedal, when the CEL is off, the throttle is smooth.
Other times, the car will start normally and will run perfectly and then sometimes the CEL will come on when stopped, but with no symptoms.
MAF, O2 Sensor, or something else?
