1999 GS300 - CEL codes P1120 and P1121
VSC, VSC OFF, and ENGINE Lights would come on, followed by my car going into Limp Mode, where only that last 25% (if that) of the throttle would respond (basically have to floor the pedal to even move at all).
P1120 - Accelerator Pedal Position Sensor Circuit Malfunction
P1121 - Accelerator Pedal Position Sensor Range/Performance Problem
I found a solution post here: http://www.fixya.com/cars/t1282822-9...es_p1120_p1121
That post claims that replacing the Idle Valve Motor fixed the issue.
You'll notice I quoted that post because he stated my problem clearly and exactly.
Side note - Here's the rabbit hole that led to this post: https://www.clublexus.com/forums/gs-...fe-to-use.html

This thread has two users who fixed it by replacing the LEVER ASSY, THROTTLE - 22060-46010.

But that's $300 http://www.toyotapart.com/22060-46010.html
That's a big number.

Can someone explain how I would go about replacing the entire throttle body? http://www.ebay.com/itm/1998-2005-LE...-/200965902948
