    04 Explorer Sport Trac
    So, I'm a Ford guy, and got my hands on a 2004 Explorer Sport Trac. Put on some bells and whistles, including 2 seperate sets of lights. I originally tapped into fuse #25(cluster and 4x4), which I am now severely regretting, as it has caused a parasitic drain I must hunt down.
    Once the battery started to drain, (and before I knew I had caused an issue), I ran through the whole charging system, and replaced the starter in doing so. It was at this point I discovered the true issue, but all of the damage has already been done. The starter I originally put in was no good, grounded out, and caused the fuse #8 in the power distributor box to blow. I replaced the starter, again, and now it will start the poor truck, but the first crank is super hard...as in, it cranks, heavy pause, then starts up. Oh, this can't always be reproduced, as sometimes it starts up like on the showroom floor.

    Last, there is currently showing P0301, misfire on cylinder 1. It isn't really noticable, except on startup, and during hard acceleration, where there seems a slight hesitation. I checked in the bay, and it might have been due to the ignition wire touching the other engine parts, so I took time to ensure they are all isolated.

    I need help, please, (and I promise, moving forward, to always tap with an inline fuse, straight from the battery).

    P.S. I also cleaned the MAF with the specialized cleaner from the local auto parts stores.
