These cars have a history of issues with the transmission slipping, and many needed new transmissions. The vehicle would need to be road-tested to see if the issue is with the transmission slipping, or if the engine is misfiring. I recommend that you have a mechanic, like the ones from YourMechanic, come by to determine the cause of the RPM problem.
