My 2010 chevy traverse seems to idle high while I'm driving.

Customer Question
My 2010 chevy traverse...

My 2010 chevy traverse seems to idle high while I'm driving. When I pull over, put it in park, then drive, it performs as normal. what's causing this?

Mechanic's Assistant: How many miles are on the car? What size is the engine?

126,624 miles v6 engine

Mechanic's Assistant: Are you fixing your Traverse yourself? What have you tried so far?

I bought the car used so the warranty is long gone. I took it to Firestone yesterday. they said it needed spark plugs and and an engine air filter. $539 of what seems more like maintenance later, i noticed the same problem again this morning.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Now my stabilitrak and ABS lights are on when they weren't before. I am also now getting a messaging that the traction control is off as well as my all wheel drive.

from what you describe you have an issue with the throttle body and or accelerator pedal.

do you own a scan tool or is the check engine light on as well?

check engine light was on when I took it to Firestone. Today's off but now, the ABS and stabilitrak lights are on! It's also now reading that I need to service my traction control and All Wheel Drive is Off too.
Chevy Mechanic: Lou P., ASE Certified Technician replied 5 months ago

you have an electronic throttle body that limits the throttle based on accelerator pedal input, well the motor can fail or the throttle body can be gummed up , since there is no cable the motor that runs it must meet certain positions , if it does not then the lights you speak of will come on because the limiting of the throttle is actually part of the traction system.

yeah all of those can be tied into the throttle body, did firestone run the fault codes do you know?
