Hey Everyone, New here to the forums, bought an 02 mustang a year ago and have always had an engine vibrations in higher gears at lower rpms. I have now replaced my coil, plugs and wires and the problem still persists. I reved the engine to around 1700-1800 rpms in neutral and am able to start the vibrations. However, I kept the idle very steady at 1800 or so rpms and can notice that the vibrations comes on and off. The vibration comes on for about 16 seconds and dulls out to no vibrations for 8 seconds and than again vibrations come on. The car will do just that for as long as the idles held around that range. Can this be from a crank position sensor or something else similar?
