I have an 82 Trans am that I have installed a rebuilt 4bbl Rochester carburator a new fuel pump and an egr valve. The car is getting fuel to the carburator but won’t stay running. I have checked the choke and it seems to be adjusted correctly. I have checked all vacuum lines and replaced some lines and don’t find any leaks. I am stumped and would greatly appreciate any advice you can give me.
Thank You

--Check the fuel pressure before and after the fuel filter if its within specs if okay-double check the carbuerator again-something is wrong

Im not sure how to check the fuel pressure before and after the fuel filter. I did put a new fuel filter in the carb because who ever rebuilt this carb had installed a little screen instead of a fuel filter. I havent adjusted the idle screw any is it possible its set to low?

Thank You

Re-adjust the A/F mixture and Curb idle speed and see what happens
