I got the fuel pressure regulator installed and it does seem to run a little better and nowhere near as rich, however the problem is still there and I cant get the car to idle. I have the regulator set to 6 psi. I pulled out all the idle mixture screws and sprayed some carb cleaner in there and into the air bleeds as well. Does this sound like an idle circuit problem? I still cant get the car to idle by itself to see if everything else is okay.
