2001 Ford Mustang Repair Question
The car is idling very very rough
first, check the compression. then the plugs, not just one. the wires need to be ohmed out, not just looked at as they could be broken internally.
the injector need to be checked along with the wiring. as lastly, look for vacuum leaks as that may also be the issue with the high idle. if not, the idle control valve may be bad
