Hberres Posted September 15, 2015 Report Share Posted September 15, 2015 My 03 xc70 has started to rev the rpm's quickly while driving. It happens so fast I haven't been able to see how high its jumping but it goes back to normal instantly. I've only had the car for about 4 months. 134,000 miles. Any suggestions?
