My car has a rough idle only when it's in park and I bought mass air flow sensor cleaner and I cleaned it and put it back in and then I started the car again and the idle sounded smooth and then I cut it off and came back twenty minutes later and started it back up and the rough idle was back and I was just wondering if there is a way I could fix it and if it maybe something else other then the sensor

With rough idle problems we need to start with a compression test across all cylinders, I rough idle could mean one of the intake valves is leaking.
