i have a 1996 mustang gt. just cleaned throttle body replaced egr and iac valves. my car is idleing better now but when i take the rpms past 2k on the way back down they get stuck right at 2k what sensor could be causing this now. i have no engine light on too>

You may want to check the throttle position sensor, it might be failing within spec
