For the past few weeks I've been trying to figure out whats wrong with my 1995 Ford f150, it was running fine on the way to work. Upon leaving that night, it seemed like it was going to stall a few times, but made it home alright. The next morning it ran real rough and had poor acceleration. After that it wouldn't idle long before dying. I've replaced the pcv valve and a vacuum line that was cracked, there was no change. Than I cleaned the IAC, which had some build up, the maf sensor throttle body, and the egr valve which was also kinda gunked up. After cleaning, the car ran great around the block a few times and then the next day it started dying again. I ran some sea foam through it, the car ran better temporarily then started acting up again. The one other thing it does is; very sluggish acceleration with a clanking sound, until it gets over 15mph or so. Any advice is greatly appreciated! Thanks

My truck specs:
1995 Ford Truck F150
1/2 ton P/U 4WD 5.0L EFI 8cyl

 

Anybody have any idea of what might be wrong with it and what the clank sound might be?

 

You need to check and pull codes first. That would help us point you in the right direction.

 

Thats the other thing thats weird. The check engine light isn't on.
