This truck I got seems to have a lot of new parts on it including the fuel system. But it shifts late and hard.
I've read lots here on the subject and I'll have a new (black stripe) adjustable vacuum modulator tomorrow.
I did pull the hose off the modulator and it wasn't wet with fluid but I'm going to change it out anyway since it looks old.
The vacuum pump looks new and I got 26inhg off the hose with the red stripe using my Mighty Vac as my gauge.
I'm not sure where all the hoses go from the vacuum "manifold" and if this truck still has a VCV or that has been changed.
I labeled some pics and I hope y'all can let me know what I'm looking at.
The red arrow in the 1st pic is where I think the vacuum line from the "manifold" is going to the IP. I didn't have time to pull the air cleaner to be sure.
I don't know what the thing on the right side of the 1st pic is (blue arrow) but there is a chance that is where the vacuum line is going from the "manifold" and not my red arrow.
The 2nd and 3rd pic has a hose I labeled ELEC and that's where I measured 26inhg from. I don't know what the thing it's attached to is. It has wires coming out out it.
Any/all help appreciated.
