    The older fords , like in the 90's , had a re-learn procedure

    I doubt his 2005 needs to re-learn

    They all adjust and learn as they go..A GM is pretty close at default/ before it has to learn...then it trims fuel and the stepper motor for idle
    Some other makes may run rich and have a high idle for several minutes

    But while we're talking: how is that "resetting" process accomplished anyway? <g>

    Unhooking the battery for a spell should do it.. .some newer vehicles don't respond to this ...but since your is several years old it should.
    It's free and worth a try.
    That will give you a fresh start (pun /no pun).

    Every system controller has a short-term fuel trim which must be re-learned under OBD2.

    But..... that short-term fuel trim has nothing to do with the problem that you're experiencing.

    I think you indicated that you noted that the distributor rotor was once in the incorrect position, and then when you checked again it was in the correct position.... so I'd want to pull that distributor and shine a light down in that hole and watch that camshaft rotate while somebody else cranks the engine over by hand.

    In what could be a related story.... I sold a 69 Corvette that I had modded out in 1971 to a fellow who was an officer on board a naval submarine, and he was driving from outside of Philadelphia up 95 to the sub base in Connecticut.... and while he was going through the Bronx the engine stopped running so he had to have it towed to a place where it was going to be stored while he was on duty for 6 months, and he took the train up to the sub base.

    So he comes back from active duty and has the car towed back to our little town outside of Philadelphia...and it turned out that the distributor gear had broken in half and fallen down inside the engine block.

    Now mind you, this was the 427 rat motor, but metallurgy hasn't really changed that much.... so I would want to look at those gears and their mating surfaces very carefully.

    That would be a funny retribution.

    I have a 1000 square foot carport with a bunch of stuff stored in the rafters. Squirrels and birds always found it a handy place to have nests. I am live-and-let-live and we co-existed for years. Then maybe ten years ago the squirrels decided that they owned the place and I had to get out. They would always come out and scream at me and eventually one of them pissed on my head while I was working on my boat.

    That was my Sand Line and it was ON. From then on whenever they made a sound I ran out and threw 2 by 4 chunks at them, poked them with furring strips, beat them with sticks, chased them across the lawns and down the street; me screaming and bellowing the whole time. And when they raced up a tree I kept throwing stuff and tossing furring strips like javelins way up into the trees.

    Although I hadn't screwed any rat traps to the trees yet - I guess they knew how serious I was because they mostly decided to relocate to somewhere less risky. After that I installed a standing seam metal roof and then they couldn't even cross the yard without encountering me.

    So maybe the squirrel grandsons all got together and came up with the idea of chewing my van wires to even that old score. <g>

    I've seen no evidence that they have but I'll have a closer look when it dries out.

    I have seen some Ford distributors almost lock up damaging the cam gear as well.
    The distributor may turn fine once out and in your hand ...but pulling and pushing on the shaft while rotating will have a very tight position...bam..bad distributor.

    I didn't know PHMs had (slipped) time at the distributor...if it has then the gear for sure... Hopefully it is just the distributor gear and doesn't take out the cam like some Ford's do.

    I also suggested checking the timing as well due to the backfiring...which could save him from pulling the distributor and looking...he would need to retime after reinstalling anyway..so just as well check it before hand...if the timing is not correct then pull the distributor.

    I did try to manfully move the rotor with the distributor installed but it was solid - it might have 1/16" of rotary play in it.

    I also pulled the relatively-new distributor out and try to make the rotor and the bottom gear move independently - but I was not successful: they were both solidly connected to each other.

    And I peeked down the hole the distributor normally lives in but I really couldn't see anything which looked meaningful. I was expecting to see the cam gear but maybe it's full of oil or something.

    My god, I wish I was your neighbor about ten years ago.

    The cam gear isnt in oil..kinda hard to see down there as a flashlight will be in your way if you try to look straight down the hole.
    Since you had the distributor out ...you may be off a tooth or two upon reinstalling it..unless you indexed the rotor beforehand....but none the less
    Check your timing now since you had the distributor out.
    If you can get the light just right to see the gear you can see down there ... It takes two crank revolutions to equal one cam revolution...so look in hole. Turn engine a half turn.. which will give you another quarter view of cam repeat until you have two revolutions on crank..I would start with the timing marks lined up so you know where you are starting from.

    If youre not sure where the dizzy drops back in , I can share my trick to finding TDC

    Remove # 1 Plug

    Hold your finger over # 1 plug hole

    Have a friend bump starter

    Ok so you will feel a slight pressure when the Exhaust stroke pushes on your finger , dont be fooled , but when the Power stroke comes around there will be No question ... it will shove your finger off like mad with a loud hiss

    Sometimes the engine goes around too much , so have them bump it around again , go past the exhaust stroke , and this time stop as you feel the big hiss coming on

    Now align your Harmonic balancer with 0 , it should only be an inch or 2 away

    Then ofcourse drop the dizzy so it points to # 1

    Soemtimes it wont drop in all of the way because of the oil shaft , so I make an educated guess where it should land , and bump the starter while pushing down , and it falls in place

    Then stick your finger over the plug hole once again to find TDC , and verify the dizzy is pointing at # 1 just to be sure

    I for one am eager to hear how this one turns out.
