1997 Ford Pinto 6 cyl Two Wheel Drive Manual

Car starts hard, runs rough at an idle, Check engine light on and sometimes flashes. I replace the coil pack, plugs, wires...... Code still comes back

A specific misfire on a cylinder should lead you to check the plug, compression and injector for that cylinder

Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
