I have a 1996 Ford Explorer, and it just started revving on the freeway at 1000 rpm 's.
When I tap on the accelerator, the winding revving stops. The temp. gauge goes up while
it is revving, and it is worse if I use any heat, flashers, blinkers, brakes etc. I am
wondering if this is a relay issue? I ask this after reading other questions, I will take your
answer to a mechanic. Thanks.
