Problem with 1989 F150 5.0
 

i just got it running after a year or so of sitting
i put new spark plugs cleaned da KN airfilter, had to redo all the broke body bushings, new fuel pump, new starter etc etc you know the works :P

so i got it to crank but real rough back firing and ****
so i found the #1 position matched it to #1 on the disturber, and she kinda smoothened out she will run on her own with out any gas now
but if u try to drive it she doesnt have enough power for it to drive gotta floor it when u let out the clutch and it only hits like 1,000 rpms.. what could be the problem?

Check the fuel pressure.

Or fuel filter clogged.

That's within specs. I'd check the codes next, probably would have done that first. :D
