Ford Engineers suck and having hope will keep you from ripping *all* of your hair out.
So a 24 year old truck that has had systems deleted by previous owners and a rebuilt engine with a camshaft that may or may not be computer friendly is the fault of Ford engineers?

My4FordTrucks has a point. I mean these old trucks can easily survive over 20 years with minimal problems. Mine is a 1994 so thats 27 years in itself. On these older trucks anything that goes wrong is usually user error. My buddy has a 1990 302 f150 4x4 that he beats to **** and is at WOT everywhere he goes. He's going on his 3rd differential. But not everything lasts forever.
rla2005, is it safe to clean the IAT sensor? I pulled mine to take a look at it and it looks disgusting but not as bad as some that I've seen online. It was pure curiosity that lead me to pull it out and check it. Even though it looked like it was changing voltage correctly, you can never be too sure of things.
The ACT/IAT on my old F350 w/5.8L engine was worse than that. I used an electronic contact cleaner to shine it up. It measured fine with a meter afterwards.

Well all I had was TB/Carb cleaner, which is just like brake/parts cleaner. It looked damn near brand new after that. I haven't taken it in a drive yet but will soon

I typed that out tired and blank minded trying to crack a joke to fill in for my inability to think of a valid response. I failed.
Stupid comment on my part. I don't know why I even submitted it.
rla2005, fuel pressure is normal. Over 40 psi with vacuum disconnected, around 30-33 psi with it connected. Rises over 40 when pulling throttle on engine. Reads the same with both pumps. Injectors will hold pressure after shutting it off. After shutting it off the psi will be around 38 because it isn't consuming fuel anymore. I went inside for 20 minutes and came back out and the needle barely dropped. Under 30. Anything else I should check?
Looks like it is coming down to a bad/failing computer or the O2 sensor is bad. You have plenty of fuel based on your posted values/conditions.
Well I picked up an O2 sensor from napa the other day just in case that's what it boiled down to. I'm a bit busy today but when I get around to changing it out, I'll send pictures of the one that's in the truck. The truck only has 132,000 miles on it, low miles for it's age. I bought it around 109,000 miles. This leads me to believe that the O2 sensor could in fact be factory. I mean, you'll see many efi vehicles get over 150,000 miles on mostly original parts. The truck has always been taken care of, and maintenance will make them last.
Stay posted for when I get around to it, I'll pull the O2 sensor. It's in a horrible spot. Virticle on the exhaust pipe and close to the transmission. It'll probably take some finesse to get it out.
Some say to replace the O2 sensor every ~50k miles, others 100K. Others say they do not go bad. Somewhere in between is where I stand. I do consider them wear items that need replaced at some point. Given how difficult it usually becomes to remove an original or older one I would take a peek at the computer first.
Hopefully you can get that O2 to thread out. If that's the original it may not want to. If you do get it out, do yourself a favor and use anti-seize on the new one. I once tried to remove one from the collector on a long tube header and could not get it to budge, soaked with PB blaster for a couple of days to no avail. Took it to a muffler shop and he heated it with a torch until it and the collector were glowing red and it still refused to loosen. Ended up just leaving it in place and installed another one down stream.

Damn. Hope that isn't the case for me. We'll have to see how hard it is to get out. If I'm lucky and the 02 sensor is positioned just right then I might be able to use a pry bar against the wrench to loosen it. Hopefully I don't have to. I'll crawl under there tomorrow and get a wrench on there. I'll update y'all on what I find.
