Hello all. I'm hoping I have come to the right place. I bought a new to me 2001 Expedition Eddie Bauer a few days ago. I knew it would have problems going into it but now I am getting in a little over my head. So I will start at the beginning and go from there.
I got the vehicle home from the purchase and pulled the engine codes. I got P0357, P0442, P0171, P0174, and P0307. I did my research on them and looked into what would be needed. I knew the 442 was most likely the gas gap, especially since the cap that it currently had didn't correctly click. I was right and a new gas cap fixed that problem. The P0171 and P0174 were also an easy fix. I figured it was most likely a dirty MAF sensor and I turned out to be right. While I was at the parts store buying the cleaner, I picked up an air filter too. I figured it was just safer to change the filter out and start my own routine. Turns out the codes were created because there was no filter and so that is why the MAF sensor was dirty. The P0357 and P0307 were both about cylinder #7 having a misfire issue. I lucked out here and only had to replace the boot for 5 bucks. So now all of my engine codes are cleared. Yay, go me!!!!
I have also replaced the engine oil, added some transmission fluid as it was low, replaced the fuel filter, and changed out the differential fluid. Next on my list is a transfer case fluid change.
So here are the major issues.
I can't select a 4x4 mode without blowing the fuse for my backlight on the instrument panel.
Putting the truck into any mode other than 4H results in 4x4 light being on but then not being able to drive forward.
Having truck in 4H mode results in being able to reverse but not more than at an idle speed, however the truck will drive forward just fine. The 4x4 light does not currently come on in this mode.
In A4WD it reverses better, but slips while trying to go forward. The truck just won't move forward.
I am assuming spinning the knob all the way to the left is A4WD and to the right is 4L. I don't actually know as I am missing the knob and have to use some pliers to turn it.
The wife noticed while I was cycling through the gears while filling the trans fluid that switching gears had a loud clunk sound, like a binding sound. Almost like when a brake pad sticks.
I also can't get the gear selector to go low enough to get the truck into first gear.
I don't know if any of this is related or if it is all related. I am just looking for anybody that could by chance point me in the right direction of what I need to look at.
Thanks
