well ok, I'm confused... AC Idle-Up VCV

it's the little things that bother me on a daily basis with my 91 22re

recenetly my truck's been idling WAY low with the AC on, after replacing the idle-up valve on the intake, AND the VCV on the valve cover, and it still didn't want to kick the RPMs up with the AC switched on

odly enough, every once in a while it would kick on and work! my idle would raise up everytime the AC clutch engauged. Then at random, it would just now work again...

it hasn't been working at all for about 2 months now

well today on my lunch, it randomly started working again!

took a few short trips this afternoon around town after work, and it's still working!

I have no idea what's going on, but I know sure as I'm telling you guys this now, it'll not work tomorrow


anyone else had this happen?

that's the only thing I can rationalize...

I temped to just run a direct jumper wire from the AC clutch engauge wire to the VCV
