l have a 2006 Nissan Altima l decide to have the throttle body clean and now l am getting engine service lights (code P0507) l clear the computer many times but this code comes back P0507=idle Speed too High)

you adjust the idles speed down with a straight screwdriver it should be near the throttle body

there should be an idle air control motor that is what is probably sticking

Your car has a ''fly by wire'' throttle system which means it uses an electronically controlled throttle. When u manually force open the throttle body plate it messes up the calibration of the electronic throttle control actuator. You need to take it to ur Nissan dealership & have them do a idle/air learn procedure on it & hopefully that will fix it. If not u will have to replace the throttle body. Here is the part number for the throttle body 16119AE01A & it will cost u around $594 unless u can convince the dealership to cover it under warranty. If u do take it to ur Nissan dealer do not tell them what u did to ur car or they will not even attempt to get it covered.
