Erratic idling in a Ford Mondeo can be caused by several issues, including a dirty or faulty idle air control valve (IAC), vacuum leaks, or problems with the fuel system such as a clogged fuel filter or failing fuel pump. Additionally, issues with the ignition system, like worn spark plugs or ignition coils, can also lead to inconsistent revs. It's advisable to have the vehicle diagnosed by a professional to pinpoint the exact cause and ensure proper repairs.

What causes your car to reve excessively while the RPMs stay the same?
that is impossible. "rev" is short for "revolve", RPM stands for revolutions per minute. your engine cannot rev without increasing the rpm's. the only thing i could think of that would resemble rev's would be a bad fan clutch which would make your fan spin erratically. newer vehicles use electric fans which could also resemble "rev's".
