5SFE High Idle Options

[cyberblader1130]

I've been scouring the net using google, toyotanation and 6gc.net. My 5sfe is currently idling at 1200-1400 rpms and i can't seem to lower it by any means.
So far i have.......
- Cleaned the Throttle body and intake manifold the best i could
- Cleaned the IACV + tried adjusting the plate at the bottom both ways - Idle soars to 2000 then pulsates then adjusted back.
- Replaced the majority of vacuum lines
- Checked the MAP, IACV, FPR
- Checked and adjusted the TPS

The lowest rpm i have managed to obtain has been 1100 and know the stock is around 800.
Anyone have any ideas?

Off topic but might be revelant, i also changed Cap + Rotor, Spark Plugs (NGK double platinums) and Harmonic Balancer (The crank pulley i removed looks nothing like the new one??? Much larger and heavier in comparision.) 2 New belts as well.

Speedo works great, i cross checked it awhile back with a GPS unit so its fairly accurate and the cruise works too, used it a few days ago on my way to work.
Car is currently idling at ~1200, it did drop rpms when i covered the IACV hole in the TB though. Is that a sign of a bad unit?

Mine would idle at 1100 when my thermostat was bad. Its an easy change and its always good to make sure its in proper condition after a while anyways.
