Blacktop 20V high idle
Anyone have experience with this?
My blacktop idles at 2000 rpm. Only there is a catch. Sometimes it will calm down to 1000. But when I rev it up it will stick again at 2000. My first step will be cleaning the ISAV (i.e. ISCV). A sticky bi-metallic spring could cause a high idle. It pushes open the valve to the bypass air intake. However... it does not make sense to me because once the engine is hot, that bi-metallic spring is not moving anymore right? It would be fully expanded. And if it's not moving, how can I have 2000 rpm but sometimes 1000? I also read that there are two solenoids in there, connected to the ECU. As I understand it they make sure the rpm is stable under various loading conditions (also by controlling the valve to open the bypass air intake). Can the ECU also "command" a 2000 rpm? That it somehow thinks the engine is still cold? |
