  1. I drive spiritedly even on a short trip. Once I get all the right tools in. I'll be doing a thorough carbon build-up cleaning on the intake valve on my car. Last I did an inspection. I found a lot of carbon build-up on the intake valve on my 2nd gen traverse. Seems the 1st owner only drove short trip mostly and had a lot of carbon build-up on the intake valve.
