Hey, I never got a notification of this response. It's been awhile, but things are better. I did end up replacing the MAP sensor when I had the intake plenum off. I am looking at injectors now to fix the hot start issue. The plenum will have to come off again, but it's really not that hard. I've never done injectors before, but it looks mostly straight forward.
I also redid the entire AC unit, compressor, condenser, dryer, and upper AC hose. Works like a dream.
I also had to replace the radiator.. it was cracked internally.
