The van engine is running rough.
Quite a few things can account for an engine running rough. It could be just one cylinder misfiring, or multiple. If the Check Engine Light is on, the computer has detected a problem and the code(s) will help narrow it down. The most common would be ignition problems. Spark plugs, wires, and coils. It could be fuel pump or injectors. A large vacuum leak or mechanical problems could be the culprit as well. If you would like this repaired, I would recommend having a certified mechanic diagnose the cause of your engine running rough.
