Hello guys i need your Help My car has a lot KR i don't know what the problem is.
Car has approx 45k miles and has H/C/I and Tune from katech i dont change anything, and the car runs fine, but for the past 6 months i have had issues with KR.
I don't drive so much often, approx. 2?3k miles in the year with this car, and i run only 102 octane pump gas fuel ( in USA, like 97?98 octane)
I Already changed all spark plugs and checked the spark plug wiring.
