Re: 94 formula firebird gas issues
remove the vac hose to regulator plug the hose run it see if it still has excessive fuel in exhaust .

another reason is exhaust leaks must not have any leaks

then the O2 sensors may be damaged [wiring] because of the headers ..
94 is a PITA to see codes/engine fuel trims etc...
