Car is 93 Prelude, stock h22a1. I removed the throttle body to gain access to my heater core. I didn't remove any of the coolant or vacuum lines, only unplugged the sensor (TPS, I believe) When I put the car back together, I now have a high pitched whistling sound and the idle is screwed up (rev to 2.2k and then back down on it's own like a bad IAC does) The whistling wasn't there when before I removed the TB and it idled fine as well. Did unplugging the TPS reset something?
