My idle is a little higher (around 900) after getting 555 cc injectors and ECU upgrade by JWT. It is NOT erratic, it is very consistent, just high. All my IAA tubes and connectors are clean. The idle adjustment screw does not seem to do anything in any direction. Is the idle speed controlled by the ECU in part?

Is it normal to have slightly higher idle with 555's? - Quick_Z09:51:21 02/24/05
