Hi all ...any ford techs out here... i had a windstar in the shop few weeks
ago , running on 5 cylinders , no spark on one cylinder (3.8 lite engine )..
but PC wouldn't set a missfire code , customer said its been like that for
over 2 months , he fiduard it was do to having over 260,000 miles , but i
found a bad plug wire on one cylinder ...so my question is why didn't the
pc pick up the missfire and set a code ? what triggers a missfire code , i
thought it was off the crank sensor , seeing RPM decrease ...when it
should be an increase .... i know fords are slower at setting missfire codes
than other manufactures but this was 2 months , guy drives alot , other
fords with 4.6 and 5.4 with coil on plug pick up missfire faster with in
minuets long minuets have had them take ove 5 mins to set a code , dodge i
hate to say is way faster , any ideas ?
