so i finally got my new to me 87 GN on the street. TT chip, egr delete, 60 injectors, exhaust and cold air intake. The scan master shows iac at 02. Is this normal?
46No its not. What is your tps #

That most likely the throttle plate it’s opened too muchWhat would a low iac number indicate?
No i dont. In car right now, how do i adjust them?Both are going GN to be adjusted at the same time.
You know how to?

Thank u, will do. On a sidenote. Is itjust the nature of these cars to have a harsh vibration and rough feel while idling? My car doesnt seem very smooth.Set the IAC then the tps . Open the throttle blade to lower the IAC number close it to raise them . With the screw that was circled in a pic
I do notice the egr block off isnt sealing very well. Is there a better way to block it off ?If the IAC was good but is now low, that would indicate a vacuum leak.
