Simon Posted January 15, 2013 Report Share Posted January 15, 2013 Sounds like the base idle position is too high. (base step position) This will cause the idle to sit too high on throttle close, the ECU will then lock out the idle control as the RPM is above the rpm lock out.

Simon Posted January 16, 2013 Report Share Posted January 16, 2013 Yes bigger the number the more fuel. You will need to have smaller numbers in the step position table at cold temps and getting bigger as the car warms up. This is due to the position being steps from fully open.
