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.

I took it apart one last time, cleaned it thoroughly again. Reinstalled everything and started it up, it ran high to 2000, then settled to 1200. i sprayed some carb cleaner with my thumb over the IACV hole and saw it seeping in through the throttle body i thought was closed fully. So i backed out the idle screw and now is idles around 900 and sticks a little bit.

Much better than before but now the car jerks significantly more when the gas is pressed + released while driving. Isn't quite as smooth as it used to be.

Edit:
Problem was not fixed only covered up by a lower idle so i returned the idle back to where it was. (would still pulsate and idle high.) At the time i was also checking the ignition timing and i believe it was somewhere around 17* BTDC and once i returned it to the stock 10* BTDC the idle returned to normal. How the ignition timing got that way ill never know but at least its working a little better. I'm still thinking my IACV is shot so im going to pull one from the boneyard.

Did you get it fixed? I was trying to clean my EGR valve and Modulator today couldn't get EGR off then i put everything back. Turned her on and started idling 1000-1100.
