Can the idle control valve make the vehicle act like the transmission is slipping?

I describe the problem to you guys earlier about when I turn on my air-conditioner the RPMs of the vehicle go up-and-down up-and-down until it eventually dies. You guys told me it could be the idle control valve or a vacuum line. Well now the problem is getting worse and I was wondering if the idle control valve could also make the vehicle act like the transmission is slipping?

poor engine running can effect the way a trns works. try cleaning throttle plate on both sides and iac hole with choke cleaner then check fuel pressure with a gauge 60-66 psi key on engine off autoparts rent it.
