I had the battery disconnected for over 45 mins. I restarted the car. It did not stall out but kept emitting smoke out the back and the fuel smell was still in the air. The engine stayed on but went from close to stalling out to almost revving itself. I didn't apply any gas pedal and kept it in park. After 3 mins I shut it off. Engine was going up and down the whole time. When I received this used MAF today they're was a lot of dust on the inside of the container. I wonder if it doesn't need a cleaning. Not sure what to think now.
