Mostly happens in the mornings.

After the secondary air pump has stopped, i put the car in reverse and the car tries to stall. At the same time it also makes a popping sound which i think is coming from the airbox/intake.

Its got me puzzled? Once its warm in runs perfectly.

Anyone know what could be causing this? Its a AUM on a 02 plate btw...
