1993 ford ranger rough idle fix *HELP* Sign In

Here's a link to the video of my trucks problem. http://youtu.be/IbXogsIl5rk
My truck has been having this problem for about two weeks now and i replaced some parts (listed below) and it still hasn't fixed the problem. My truck has a rough idle at stops and it stalls if i dont give it has and if i press the pedal quickly it bogs down and sometimes i here a popping noise. I recently found a vacuum hose that wasn't connected to anything and its on the passenger side and i cant find where it connects to, i showed it in the video i attached to the post. Please help me fix this! Its my daily driver
Parts replaced:
New throttle position sensor
New spark plugs and wires
New pcv valve
Cleaned throttle body
Cleaned MAF sensor
Checked compression on valves and they are good
Cleaned airfilter

What is up with that MAF sensor jerry rigged thing you got going on there?


If you put the MAF back, like it was, bolted to the air cleaner housing how does it run?

That vacuum line probably goes onto the end of that barrel shaped plastic tank which is a vacuum storage tank. That engine really sounds like it either has a plugged converter or the timing belt has jumped a tooth.

What led you to believe the fuel pump needs replacement? Did you have low fuel pressure?
