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!

check engline light just came on 2004 freestar?

Can you find out what the trouble code is that the check engine light is giving out? You say that there are no syptoms present with the light? Did you just fill up the gas? sometimes if the gas cap is put on incorrectly, the light will come on because the system is losing pressure. Try fixing the gascap and see if the light goes off. If not try and figure out if anything seems out of the ordinary. It is hard to figure out what is wrong if you cannot get a code or find any symptoms
