    Alright look.....my car is running rich as a mother ****er. I've been hearing that there is a way to adjust my fuel pressure. Is this true? Is this something I should be messing with? And what in the hell (if the answer to the first two questions is YES) is the right fuel pressure that I'm looking for, 38 psi? :shrug:

    What evidence are you using to conclude you're rich? You can adjust your pressure with an aftermarker regulator and gauge if you have one.

    Within stock specs is 38-39 with the vacuum line unplugged. It should drop to around 32-34 with it plugged in.

    This seems like it should be in tech btw.

    What evidence am I using? Well, the fact that my car smells SO bad of fumes it makes my eyes burn, my head dizzy, and pretty much leaves me smelling like a gas tank for the rest of the day. I'd say it's fair enough to assume I'm running rich. :nice:

    Unless my calculations are off. :scratch:


    :D

    Is this something that is ONLY fixable by dyno tune, or am I able to lean this problem out a little myself? I don't want to mess with anything that could potentially leave my car running worse, I was just wondering if there was some kind of quick fix I could find for the problem.

    fix your intake prob first, dont go leaning things out yet!! Lenaing it out will do absolutely nothing in most cases except make it run lean lol

    Check the codes before you start throwing money at it.
