Hey guys. I have been having trouble with my turbo 4.6 running 16psi . everytime am wot i get a misfire code. thus far i have pulled po306 and po302.Not sure what to do about this. Also i have my climate control vaccum source hooked up to the stock location. So it is seeing vaccuum and boost. The problem with this is i think i am creating a boost leak through the climate controls. Could this be true? If so where should i relocate my climate control vaccuum source to. Could these two problems be related?
