Can a decent leak in my intake manifold gasket cause my car to run rich? My air fuel reads 18.0, so i am running lean but at cruise im around 14.5 to 15.5 which from what i read is ideal. i sprayed around my intake manifold after i replaced my injector and the idle damn near died. Also would this be my cause of boost loss? I am still hearing an obnoxious clicking when my idle drops low. Could this be my resistor pack for my injectors? I would unplug the injector that it sounded as if it was coming from 2 or 3, and it would stop till plugged back in. I am trying to knock away all possible reasons why my car is running like poo.
Oh i am running a AEM air fuel gauge and 18 is pegged in the red to the far right. No idea how this reads lean rich or stoich since all air fuels are different on how they read, but my numbers are ------ at idle to 14.5 - 15.5 at cruise and 11 to 10 at 9 psi under pressure.
