What causes a car for the RPMs to race when driving at a constant speed
No codes shown, I've plugged an expensive OBD
in. My car RPMs race and the car will surge usually
driving 35-40 miles per hour. Has happened
several times in the last 2 months, but since it
doesn't code it cant be fixed unless the problem
duplicates for the dealership. Is this an easy fix or
a trade in?
Car has 88,000 miles on it and has only done this
since my last oil change about 6000 miles ago ,
getting ready to.bring to Hyundai for evaluation
since I'm close to warranty expiration.
