Hi

I just want to know if there is a way to raise the idle speed with the s300

The big problem is, when it's cold, I need to push a little the gas pedal, the warm up the engine, if I dont do that, the idle speed is 500 rpm and it's stall

I have a trottle body obd2 with no fast idle and no ajusting screw (came with my h23a VTEC 2000)

The h23a came with a 3 wire idle valve, now I have a 2 wires IAC

In smanager, I try 900 rpm to 1500 rpm for the idle, no change

Thank for your help

If there is no idle adjust screw, you may need to find a different throttle body.

Fast idle valve is not needed, but may need to be fully blocked off as sometimes they fail in the open position.
