Weird vibration issue in my 1998 Escort. Please help.
I just bought a 1998 ford escort and am getting it ready to have it inspected.
For some reason at idle it has a vibration, and it vibrates more one second then smoothes out a little then vibrates more for a second then smoothes out a little.
It vibrates worse when I have driven it longer.
It's got a brand new timing belt, air filter, spark plug wires, spark Plugs, PCV valve.
Anyone have any idea on what it could be ?.
