My rpms keep going up and down but no check engine light
I have a 2017 Mitsubishi Lancer, my rpms keep going up and down but no check engine light. It just started 2 days ago and it doesn't happen all the time. I took it in and they can't find a code on what's wrong. I'm confused on what's going on with my car

Clean out air intake throttle body with cleaner. I did this and fixed it for me. You can youtube it easy to do!
