Ignition coil problematic primary feed
how many miles, how many miles for the last tuneup.????
The PCM CREATES spark. on all cars since about 1991.
the only changes are where they hid the IGNITOR.
or how may spark coils you have.
my guess, is your enigne is 3.8L just like my 08
where is the coil pack, well see those spark plug wires.
the go directly to the top mounted coil pack. see that?
the PCM monitors the rail coil , the 3.8 has a 3 COIL pack.
and each coil runs 2 cylinders. like this.
so what is the first thing to do here.
easy , put in new spark plugs.
try doing the tuneups. in the glove box guide.
page 433 , at 102,000 miles. spark plugs and cables.
mine has only 60,000 miles, and they both were bad.
spark plugs and HV, wires so I upgraded to NGK mag wires.
and new NGK plugs.
if it still fails, then try a new coil pack.
HV= high voltage wire sets.
