Nissan Repair: rough idling

Question
My 91 Nissan sentra started idling rough all of a sudden but it drives fine my repairman couldn't find the problem, any suggestions? Thanks

Answer
Hi Marlene -

Can you tell me if your check engine light is on?

If so, I would need the OBD code.

Either way, check first for a vacuum leak. Check all the hoses to see if there is any breaks, cracks, or perhaps one simply needs to be replaced.


Hope this helps -
