Q: Hyundai santa fe 2006 has trouble starting, rough idle and hesitation

asked by on December 02, 2016

think fuel filter needed

My car has 143000 miles.
My car has an automatic transmission.

A rough idle may be caused by many different things such as low fuel pressure, low voltage to the fuel injectors, dirty fuel injectors, a vacuum leak, a faulty Oxygen sensor or a dirty or failing idle air control valve. Any of these possibilities relate to fuel delivery issues that will disrupt the normally balanced air/fuel mixture that would otherwise allow the motor to run smoothly. I would recommend having an expert from YourMechanic cometo your location to diagnose your rough idle problem.
