Customer Question

I have a 2013 Chevy Impala that keeps giving me a "service stabilitrak" on the dash. It also trembles when stopped and has the check engine light illuminated.

Hi there,

Do you happen to know what code is being stored?

Customer: replied 7 months ago.
I don't know what code is being stored.
Expert:  Mike V. replied 7 months ago.

Ok

Does it run normally down the road?
Also, was the check engine light on prior to the tune up?

Customer: replied 7 months ago.
It runs normally down the road until I'm sitting at a stop light. Then while I'm sitting with the brake applied I get the notification across the dash stating to "Service stabilitrak". The check engine came after the tune-up.

Ok

Normally when the check engine light comes on it can disable the stabilitrack, this would bring the message up.

As for the shaking, without the code it's tough to know what's causing it, but since it was after the tune, it might be a misfire from an ignition coil. Either not seated tightly or possibly once disturbed it's now arcing. This could cause a vibration at idle that might not be felt over higher engine rpms.

I think I would start with getting the code if possible, it might help point us in the right direction. Several states allow parts stores to read the codes and they will do this at no charge for you. Then of course I could give you a much more accurate answer. Sometimes bad O2 sensors can cause this type of vibration as well.
