How to fix a floating idle on a Toyota 4A-GE motor

[Homem Bomba]

Finally, yesterday I fixed it, with a little help from my metalworking skills and simple tools!

In this video I showed how I adapted the throttle position sensor from another 4A-GE bluetop, that had a different prong layout (vertical instead of horizontal). I had to craft a part that fitted in the throttle body, to activate the "new" throttle position sensor from a vertical position instead of the horizontal one used by my old TPS.

I tried fixing the vertical one to the horizontal plate without machining the new part... the only result was that there was not enough twisting margin left in the sensor, causing the throttle to be stuck like 5mm after pressing the pedal, which made the engine go much slower. Due to the lack of opening in the throttle, the PWR light on the dash never came on (it stayed always in the ECON mode).

Enjoy, and tell me if this helped you!
