I have a h22a1 swapped 95. My a/c works and could used charged a little more, but when I dont have it on I idle around 1100 cold and 1600 hot... cant figure out why I idle so high. 800 with a/c on. I was thinking a vaccum leak. But besides the fact on humid days (gotta love ohio) or when i run the a/c it overheats. Im running a stock radiator with a slim fan in a mildly built car, if i get a double or triple core would that solve my issue? Btw no air in the system and new thermo and 20k on the build. So with that being said water pump and everything is somewhat new too.

The duAL core will solve you overheating problem, provided that there is not some other issue. My single core radiator was not able to adequately cool the H22. When I upgraded, that problem went away. Are you using the d series compressor for your a/c? 1600 when hot? I haven't come across a higher idle when hot. I would bump my idle up higher, but that would only mask the problem.

I still haven't solved my initial problem. I blew out all of the lines, no clogs, or other restrictions.
Replaced the condenser
Pumped down the system for over an hour. Tried to charge it and the high pressure went way up, while the low side went to 35 and the system wasn't even fully charged. Condenser was HOT!

Properly bleed system.
