Another Idle question

My car had an idle problem that would surge between 1.5-2k once the gas pedal was touched. I cleaned the IAC and the problem did not go away. So, I unplugged the connector. Stopped the surging but idle was steady at about 1.5k.....

I tried a different IAC from my other car that does not have an idle problem.
The same thing occurs, unplugged it idles close to 1k. So, the IAC doesn't appear to be the problem......My question is, I think the NG has a MAP sensor and not a MAF sensor. Is this correct? If so, where is this MAP sensor ?. Is it on the elbow leading into the TB? What is that electrical connector on that elbow.

Thnx....Vulfi
