Default 2004 Volvo RPM issues

I recently got my 2004.5 Volvo S40 2.4i back and I'm having some issues. When I'm slowing down/stopping my RPMs DROP. I mean when I'm sitting at 2000 RPMs and I let off the gas pedal the RPMs drop to 800ish in 2 seconds. Also when I'm coming to a stop the RPMs drop to below the 800 line and bounce back up. Is this normal? I've cleaned the throttle body before and sprayed the IAC sensor but it didn't seem dirty. I can take pictures or add videos if that would help. Any advice would be helpful thank you
