Questions on 30,000 mile service

Nothing's missing now. My Ford van called for new plugs at 75K miles.
Technology has come a long way since 1953.

That's a Ford, and GM, they're running seventy five thousand volts,
about twice Chrysler's coil voltage. Does your TJ still run, with the
gasoline washed dry, cylinder walls?

Good idea, especially if you every go off road, I don't care how
good an air filter you think you have, some silicone dust will get in
and melt a glass like coating, fouling the electrodes. Drag racing I
changed them every run, that is if I wanted to win.

Only has about 37,000 miles on it anyway. Runs like a champ. It doesn't have
mechanical fuel injection, the fuel cuts off when there is no power to the
injectors. Like I said, we've come a long way since the 1950's, Bill.

So seven thousand miles of miss firing would be about a hundred
thousand in wear and tear? I guess you were obvious to the fact that
Chrysler/nazis haven't upped there voltage, even with your individual
coils. they're still firing at fifties voltage.

You'll also see the difference in spark plug gapping between the
high energy Ford and GM and your fifties technology TJ.

Spark plug replacement is in the FSM at 30K. So is drain/refill
transmission and transfer case. And check the serpentine, which
is pretty cheap to replace rather than mess with.

Pick up a Factory Service Manual from www.techauthority.com. Great
investment.

Bill, have you ever even felt a 6-cyl engine misfire? If you had, you would
know that mine is not.

I surly have, this was the fastest V6 Jeep in Glamis, '77:
http://www.billhughes.com/jeep68sand2.jpg It was using your same twenty
five thousand volts to fire the plugs. Seeing you haven't felt yours, I
don't believe you can feel it miss fire, to your untrained eye it would
probably feel like the new Hemi WJ switching between four and eight
cylinders. And if you kept a log, you would notice a decrease in
mileage.

Uh Bill, is that a "Real" Jeep wave you're giving us there? <lol>
