Name is***** goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back,

Have your machanic check the throttle body and IAC (Idle Air Control )

When this gets fould up with carbon will cause you a stalling issue and low idle .

Have him check for malfunctioin codes if the check engine light is ON whhen the engine is running you may have another issue causing you this issue .

Clean the throttle body out if covered in black carbon ,use throttle body clearner or brake cleaner to clean out the TB use a old tooth brush and a rag using your finger to get the bore and plate clean ,screw out the IAC clean the pintle and bore where it sits

The put all back together and test if still having an issue use a scan tool to see if you can activate and control the IAC .as this may be the problem if still having an issue after cleaning .
