I cleaned the check valve out and made sure it was working (the car pulls vaccum through the check valve) properly. So, I don't believe it is the brake booster, b/c the car still has a shitty idle, even with the intake mani hose being capped off.

Could my idle circuit be messed up on my carb?? Is there a pump for the idle circuit that could be taking a crap?? BTW, this problem started happening when I intalled a holley red. (messed with the float bowl levels and a/f for idle and nothing has made any difference).

I presonally think it is my Holley 600 that is giving me problems.

Are you using a pressure regulator?

Yes. I have changed the pressure up and down. It did nothing. I have nooo idea what the hell is wrong with my car. I have literally done everything I can to check what the problem could be, short of putting on a diff carb. I personally think my idle circuit is screwed up. I will be putting on a diff carb to see if that is the problem.

BTW, how are the OER carbs from Rotary shack for 1/2 bridges??
