STARTED THE CAR AT WORK AND IT WAS RUNNING ROUGH HAD NO ACCELERATION. WENT INTO LIMP HOME MODE AND I WAS ABLE TO GET HOME. MY HUSBAND IS A MECHANIC AND FOUND THE WIRING HARNESS WAS DETERIORATING, FLAKING AND FALLING APART EXPOSING ALL THE WIRES. THE CAR WOULD NO LONG EVEN START.

I SLOWED DOWN TO THE SIDE OF THE ROAD (WAS DRIVING IN PORTLAND OREGON INNER CITY AREA) BY PRESSING THE BRAKES AND FLIPPING THE CAR INTO NEUTRAL BUT THE ENGINE KEPT REVVING UP AROUND 3000-4000RPM. WHEN I TURNED THE ENGINE OFF AND STARTED IT AGAIN, IT WASN'T SO BAD BUT THE ENGINE WAS STILL REVVING UP AND DOWN BY ITSELF BETWEEN ABOUT 750 AND 2000RPM. I ALSO NOTICED THAT THE CAR HA…
