Check engine light on?

My check engine light is on and every once in a while my van will hesitate and act like it doesn't want to go at stop lights.

My check engine light is on, it cut off and hesitated when I turned it back on with a loud noise like a heavy duty truck or something.

You most likely have a clogged or worn out sensor in your engine/exhaust that is causing the engines computer to be unable to correctly adjust the engines operating conditions.

You need to figure out which code is causing the problem. AUTOZONE or other parts houses may read it for free, then use the code to figure out which part is bad.

EGR valve and DPFE sensor are most likely candidates!
