Okay my car acts funny a bit. The car in the morning idles weird. I start it after i left the fuel pump prime up and it idles automatically at 1000 when its supposed to be at 1,500. Now i dont know why it idles up then it idles all the way down . The car has no codes isnt that weird I changed my iacv. what could be wrong?????????????? this shit is puzzling could it be my timing may have jumped?
