Engine Performance problem
2002 Ford Taurus 6 cyl Two Wheel Drive Automatic 50000 miles

the computer said misfire on cylinder 1
also possibly crankshaft sensor. No engine lite on at present
miss on acceleration especially with ac on
idle smoother with warm engine
changed plugs on cylinder 1 and 6 no improvement

1. Book says all sparkplugs on ohc have coil on sp plugs. Not this '02 all apparently on the left side of motor in 1 location
2. I can change out remaining plugs and wires but I suspect vacuum leak or ignition coil

Check the compression and injector for cylinder no.1 If its the coil it'll affect all cylinders.

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
