Sorry Ron, had to run off to class!
In order to answer your question regarding the gap, I have to confess a really
stupid series of comical (and expensive!) blunders... The last time I changed
out my cap and rotor I installed the cap 180 degrees rotated (I know the tabs
are keyed to prevent this, but I managed to tighten it down anyway). Anyway,
when I fired up the truck it basically shattered the rotor and cracked the cap.
I quickly pulled everything apart and got a new cap and rotor and reinstalled
them (correctly this time), however, when I fired her up she ran like total
crap, bucking, spitting and misfiring. Could smell lots of raw gas. So I tore
it apart again and reinstalled everything but to no avail. At this point I'm
thinking the distributor and ignition is all messed up. So with the exception
of the exhaust and K&N, I took off all the aftermarket goodies and had it towed
to the dealership.
I was afraid to tell them what happened at first, hoping that maybe it would
fall under warranty. So the tech pulled the valve covers, checked for bent
pushrods, checked to make sure the pistons hadn't kissed the valves. Finally I
fessed up and told him what happened. Well apparently when the rotor shattered,
real fine pieces of plastic got down onto the camshaft position sensor and the
sync signal generator and basically ruined them..This was causing the injectors
to misfire and pour gas into the intake. The Dodge tech replaced both above
items, the cap, rotor, pulled cleaned and regapped all the plugs and did a
compression test. The compression was within tolerances and there were no
obvious bent pushrods or other damage. Definitely scared the sh*t out of me
though.
Tech spent approximately 10 hours on the truck plus parts. Service writer felt
sorry for me and only charged me $360 bucks for everything
So....... That is why the plugs are gapped at stock spec!
Feeling Foolish now!
