Hi, My name is ***** ***** for the delay.
I will do my best to assist you
i wouldnt think the air injection is doing this,,
from the way you explain,it sounds as if you may need to test the fuel pressure,,these must have no less than 60psi at all times,,it sounds as if the fuel pump is weak and doesnt have enough pressure under load..
i would think you will need a new fuel pump
test the fuel pressure
Key On Engine Off ................................................... 60-66 psi
