Keep in mind many of us entered the IDI pain funnel like you. These trucks are ~30 years old, most have +150,000 miles, and many were not well maintained by the prior owners. So it’s one thing after another the first few months. But they are Ford tough and with some love and tlc they are good runners. They are generally easy to work on.
BTW my 2007 F150 gasser I bought when my other truck was stolen was another pain funnel! (Tranny, brakes, PS pump, alternator, coil packs, fan resistor, etc.) But now the last 9 months it’s been trouble free.
That is why I take my time and shop for a deal on used cars, otherwise right now I would be $3,000-4,000 upside down in my truck vs $500.(Maybe not even that with these stupid COVID used car prices.)
It is sad and I mention this all the time. You just can’t assume a new part or rebuilt part is going to work out of the box. You actually need to assume it is not going to work. Then if after you complete the job the problem is not fixed, you know likely the part you replaced is bad.
Bottom line glad we all could help you get over the hump and running again.
