Engine Performance problem
1995 Ford Contour 4 cyl Front Wheel Drive Automatic 77,000 miles
My 95 contour has a distinct vibration when idling in drive or reverse. If you shift into neutral or park it goes away. When the vehicle is moving it goes away. If I power-brake and apply little gas while stopped it goes away.
I had it looked at by a transmission place, suspecting cv joints or possibly transmission mount, but no luck there.
What could this be? A vacuum leak maybe? Or the idle needs to be adjusted? Tried to adjust but couldn't see how to.
