2007 Nissan Quest - Rough idle

Rough dile. Down shifts hard, computer reset and runs fine until check engine comes on again.

Have the codes read and post back with the code numbers you get.

^This +1. The fact that the check engine light keeps coming on means there’s a problem. When it comes on the vehicle’s computer stores a code, which provides a clue to what’s wrong. Have the problem fixed and no more check engine light, no more rough idle.
