LOL.Ok well it seems I'm alright.

How can it be the IAC valve? Only air passes through that?

I did that little mod thing on the IAC, and jeeze. My idle wouldn't drop past 1100rpm. So I put in the stock gasket and all's well. That sux about the O/R x pipe.

Hahaha yeah that was funny.

I just couldn't resist turning it on. I usually ONLY drive with my car with the windows down, but yesterday was particularily sizzling hot outside. I needed something cooler than the air from outside. I almost never us my AC.

ya the a/c only kills horse when its working...when its off all it is is a FREE Spinning pulley...no load whatsoever when the a/c compressor isnt working...so when racing..just dont use it.. jeez...and if u think im wrong...take off your belt...spin the pulley...moves pretty damn free when the clutch is not engaged ...

moustiure builds up on the HIGH side line because its so cold...and hot outside...so evaporation takes place outside the line...therfore creates water that sits on your line then drips off onto your exhaust bc the lines run aboce the manifolds..kinda...on a HOT day...run your AC in a bit..pop your hood..look and feel the a/c lines..one will be FREEZING cold...hence A/C
