    Actually I'd say check the throttle to see if it's being held open. If so unhook the cruise control cable (if it's messing up it couldl hold ya open) and then check the throttle cable for binding.
    I drink..so consider that when reading my posts.

    There's 2-3 things that can control rpm.

    Throttle position sensor (which if it was maxed the pcm should see it and toss a code)
    IAC, could be stuck open..that can do it. I'd pull it and clean it.
    Throttle plate..you've confirmed that, so rule it out.
    MAF shouldn't because even if it lied to the pcm about airflow ...you'd choke out the cylinders w/o having enough air for the fuel.
    Major vaccum leak.

    Those are both tps codes. If you've replaced the tps, it's time to trace wires

    Since you're running a N*, make sure the TPS adapter is plugged in securely. I had a similar problem a while back with my N*. The connection at the factory plug to the adapter didn't seem to be secure. I unplugged it, added a touch of dielectric, and plugged it back in. No problems since then.

    Glad I could be of assistance. I just know how temperamental those plug adapters are...

    I'll be attempting to re-pin the factory plug to the N* tps plug in the future, to avoid the problem in the future.
