ok i did some research and now all i really need help with is the IACV, do i need to get a new sensor or should i try to take it off and clean it first i dont even know if that helps

also if someone has a 90-91 teg computer i could use for 5 seconds to plug in my harness to see if code 13 will go away that would be super. that way i dont have to waste my money on a new one for no reason.
