What's going on here?
2014 chevy cruze. Completely stopped and in park, rpms bouncing like this. Also light is dimming when it's happening? Points to something electrical id think but also not sure.
Other issues that I have is the car will stop reading rpms while driving completely and say "Service stabilitrak" and "Service Traction Control". Ive had it completely stop giving power to the car while driving, but not idling once as well recently.
Also likes to Bob back and forth when stopped without being in park. Overall just a lot going on 😬 any advice would be great.
