All original the best I can tell
This truck is new to me... had it about 5,000 miles.
Sometimes it runs perfect.
Sometimes it has a steady miss at highway speed when "lugging" if so, I can give it fuel and down shift and it will stop missing until it up shifts again.
The next day it may run perfect again.
I installed a new fuel pump, filters and Ford OEM blue spring kit.
I also added a jug of Hot Shot stiction eliminator to the oil.
Recently it started idling high and rough, about 1,000-1,200 RPM, black smoke and more power than I ever imagined it would make.
And again sometimes no power, and again sometimes it runs like new...
When my oil change was due I found a tall oil filter cap and a short oil filter. From what I have been told it has only been 1 oil change with the wrong cap/filter combo.
I replaced the filter cap with an OEM one and installed an OEM oil filter and changed the oil.
Everything seemed to be perfect for a week or so...
Now it's back to being erratic...
Rough idle, Smooth idle, high idle, surging and black smoke, LOTS of power at times with black smoke, sometimes no power.
So... I have no sensor data to share, can you give a likely problem?
Thanks
