I changed out the fuel filter today and ran it about 20min in the garage. No issues. I need to set the idle speed. Yeah, I need to read up on the base idle setup and figure out what I do not need to do, since the car doesn't have much from the 1989 system. I did watch the fuel pressure while giving it some slower more moderate throttle reving and I think it moved the pressure up more consistently then before. Meaning as I rev'd it the pressure moved up more in line with the revs. I think I had to give it pretty good revs to get it passed 32psi before.
When the car got to about 180 degrees I though the engine increased the idle speed, or it could have been the viscous fan speeding up and making it sounds that way.
I opened up the original fuel filter to see what was up. What I found is the filter element had come loose and was just bumping around in it. Picture an oil filter type of thing with a metal base on one side and the other end just the bare filter media glued to the exit end of the filter. It came unglued at that end.
