hmmm, engine light came on, was blinking randomly, seemed to come up ~ regular at highway cruise speed power,
def had a miss, shuddering, hesitation, roughness, loss of power etc, smelled fuel,
so google p0301 went to plugs, cop & thought the other stuff was unrelated, or seperate
went on for ~ a wk and a half and was gonna start with a cop replace #1 cyl
all of a sudden the other day, the engine smoothed out and ran normal, then the next day the engine light turned off
might still be a slight miss left over with hard gas pedal use under high(?) vacuum scenarios (or big sudden loads at low rpms) ...for now

you may want to pull the throttle body and clean the exhaust ports as they may be clogged Check youtube for a video

engine light came back on steady, still running smooth
pretty sure i know what the 401 is about, minor issue, i recently dealt with the common rubber L brackets that go bad causing vac issues & codes
ended up using clear hose i had lying around and did a magiver fix, when i had a look under the hood, i could see with the engine running that the clear tubing couldn't deal with the suction so was collapsing causing blockage
did the forward drivers side o2 sensor not long ago, wrench said that was the easier one but the exhaust would have to be fiddled with to do the pax side
figure i'd just drill a hole and jbweld an o2 bung near the other for a quick cheap fix

My guess is that it was missing during snow melt? Water was probably getting past the boot causing the spark to ground to the block and not the plug. Water evaporates, no more miss. Replacing the boot on plug 1 might help, and some of the parts houses sell just the boots for like 5-10 bucks.
Here is some info on the P0401: http://www.expeditionforum.com/f73/p0401-please-read-7920/

fresh easy #1 cop swap, dabs'a dielectric here & there
fiddle with the pcv tubing to deal with suction blockage in using a wrong clear tubing ... that had an unneeded long 180 deg bend
equals a humming no engine light so far
@mods - pix are missing from the first post, dunno if they were taken down or some prob on my end
i could prob fix if on my end, there were 3 pix that defined the codes
edit - just noticed pix gone from another thread so prob an issue on my end i'll sort out

last scan showed p0401, p0153 & a new p1151
just monitoring for now, at a quick glance, noticed the oil dipstick was sticking out ~ an inch, might be the reason for 1152
as far as 0153, just recently changed the #2 bank #1 o2 sensor
