Not necessarily. If you have an ECU with a MAP sensor you could just replace that hose with a little air filter. But if you still depend on the AFM/MAF then yes it will need to be plumbed to the intake so as not to let unmetered air into the engine.

not to bring back old topics from the dead, BUT ... has any of the members (koto?) who removed the IAC valve had any idle/driveability issues? I haven't seen any follow up posts.
I'm asking for two reasons:
A, I removed the PS and AC so the only noticeable load at idle should only be the lights.
B, My IAC **** the bed and in a moment of stupidity, I forgot to remove the wax sensor on the intake before having it powder coated so I can only assume that it's junk as well. Considering tossing the whole sha-bang as the car is only driven in summer/early fall months so cold starts aren't a huge issue.

I have cold-start driveability issues, but I can't say for sure that it's IACV delete related. The main thing that sucks is that the idle goes from an indicated 1k RPM idle to 2-2.2k once warmed up. I suspect my dashpot may have something to do with that though, because if I manipulate it manually it goes back down.

Paul doesn't run an IAC on his current car, with the BEGI cast intake mani and aftermarket 70mm TB. No A/C or P/S and little ol' headlights. He doesn't have issues, but he did want me to make him an IAC plate like I made Ed so he can add it to his system after not having it for a while.
