Expert:  david craig replied 1 year ago.

No problem
Expert:  david craig replied 1 year ago.

Okay, thanks. If the warning light is coming on, there should be a fault code stored. Are you able to go to an auto parts store, such as NAPA or Auto Zone? They can do a code scan for free. If you can get the codes, and let me know, I can help you figure this out.

Expert:  david craig replied 1 year ago.

do you still need help?

Customer: replied 1 year ago.
Yea it said that the code was p0507 and it turned off while I was at a drive thru today
Expert:  david craig replied 1 year ago.

ok, ill get that information for you.

Expert:  david craig replied 1 year ago.

the code is for idle speed higher than expected it can be caused by the following items:

Accelerator Pedal Position Sensor (APPS)
Electronic Throttle Control (ETC) Motor
Dirty Throttle Body
Vacuum Leak

I would start by having the throttle body cleaned if cleaning the throttle body does not work you will need a compatible scan tool to test the APP and Motor this would run $100 at shop
