Low idle

[plazola132]

I have a 2000 yukon xl and It is at 550 low idle and it starts shaking if I'm parked or stopped. I changed the fuel pump and filter, changed the idle air control and system cleaning also cleaned the throttle body but I have no codes

did you clean the IAC? typical sign of one being dirty or failing is low idle or idles up/down/dies
you will want to open it up and clean the heck out of it inside and out
