I have a 2003 Ford Exlplorer. It has 40000 miles and is a v6. Recently the ABS light came on. Well it never stays on so I havent been to get it fixed. Today I was in a drive thru when my car began to jump. Whe I put it in park it quit, when I put it back into drive it jumped forward. I then put it in reverse and it died. It started back up but still jumps when my foot is on the brake. Does anyone know what this could be? The jumping feels like the jumping when a car is about to die. Also while sitting still in park, the rpms go up above 1000 and then back down, you can hear the engine reving up without touching the gas.
