I can’t figure this out!! It’s driving me crazy. My RPM stays around 1500 only after a WOT pull. If I drive around normally, it doesn’t act up. Only after going full throttle the RPM stays high. I boost leak tested, set the TPS correctly, I’m simulating idle switch using TPS position. ISC motor and FIAV deleted. The throttle cable is not holding the throttle body open. The idle stop screw has no tension on the valve to hold it open. Once I do a WOT pull, I’ll pop the hood and push down on the throttle body valve to make sure it’s fully closed. I don’t know what else to look for.
S90 throttle body by the way!
