Idle speed dont go down

Hello,

I finally found right Torx key, set from 0,62V to right 0,6V. Go for little ride and everything was ok. SO I´m happy. Thanks to all for good advise.

I wish that TPS will be ok, and I will not need to change it.

inside of old TPS is grey or black



inside of new style TPS is Blue like below



A full ISCV reset will be required to make sure all electronics and the ECU are in sync.

you should not have to mess with the idle stop screw as long as it has not been messed with by anyone else. It is used to reference Zero TPS when the idle stepper motor is signaled to pull back during a full ISCV reset. otherwise with the throttle motor in normal position you would read somewhere around .68 Volts with the engine on and not running. This is why it is important to do the ISCV reset so the command is sent to retract the idle stepper motor so you can set the TPS while the throttle bodies are at Zero Position.
