SOS! Codes 22,33&53 after installing factory rebuilt en
Motor rookie here. I am nearly at my wits end with my 1993 F150 5,0 EFI! Recently installed a factory rebuilt motor, and I am experiencing the following issues. Engine starts, Idle raves high until warmed up and settles down as normal. Take the truck out for test drive and it runs great until the temperature heats up ( but still well below midpoint of normal range), at this point it starts losing power, sputtering and back firing. So far I have replaced the MAP sensor, regaped the spark plug to .054 (I was lead to believe that the manufacturer had gapped them for my truck at .040?). After that test drive with the same results we found that the passenger side exhaust manifold has a large crack directly below spark plug #4. Current trying to patch this up with some high temperature JB putty. I wouldn’t think that this is my main issue for the problems that I’m seeing, but what the H&() do I know. I have read and watched several videos a forums similar to my issues and I am not sure where to begin from here. I installed new plugs, cables, but did not think about replacing the rotor or the starter coil. Please any and help or advice would be greatly appreciated.

Of course I will do that. My apologies, it was early morning and I had been awake since the previous morning.
The following codes are what I am seeing:
22: manifold absolute pressure sensor out of range.
33: EVR valve fault/not closing properly.
53: This has 2 entry’s
O,C. - throttle valve position sensor above Mexican voltage
C,O. - fuel injector pump leveler sensor input is greater than self test
29- : This has 2 entry
C. - insufficient input from vehicle speed sensor VSS
C. - insufficient input from the programmable speed meter odometer module
29 is new to the game, I believe this could potentially have been caused by my lead foot prior to the truck getting to the point of backfiring. 🤷🏼
I forgot to ask tell you so far today I found a broken black vacuum line coming from the reservoir. I just finished preparing it. I’m gonna take it out for a short drive. See how it goes.

Did the rebuild come with the sensors on it or are you using the ones off of the old motor? And how did you set your timing? There is a plug that needs to be disconnected first to disable the electronic timing advance and then you set the distributor to the timing spec called for.
