Hello everyone, I'm Shawn and working on a 1990 f250 4x4 with the 460 in it. My problem, is when I give it gas it wants to fall on its face or die. And I've replaced the tps and that kinda not really helped it. I'm getting codes 32,41,73,74,21. These are all together I know there's a koeo/koer self test. I'm kinda stumped and don't know where to check next. Any help will be APPRECIATED. Thank you for your time.

 

Have you checked the fuel pressure ? Has to be done with a gauge (gauge costs 40 -50 $$ or you try a loan a tool program).
On a V8 you need 30 to 45 psi. KOEO you want to see over 40.
