Q: Issues with EVAP system

asked by on

I am having issues with my EVAP system. The car sputters while I am idling and has trouble accelerating. I think I need a smoke test to check for leaks.

It is very possible you may have a vacuum leak causing a rough idle and too much air on acceleration causing sputtering and rough running issues. A smoke check of the induction system would be a good idea. Reading the faults out of the engine computer can also assist in the diagnosis of the rough idling issue. You may want to enlist the help of a mechanic, such as one from YourMechanic, who will have the special equipment necessary to check the induction system and engine computer computer to locate the source of your engine running issues.
