Re: 2000 Base Firebird 3.8 v6 SES cold p0306 PLEASE Help!!!
Try swapping #6 fuel injector with another cylinder, and see if the code follows the #6 injector. While you have the fuel rail off, pressure the fuel system by turning the key to "run" (not to "start") and see if the injector is dripping.
Do a compression check.
Check the valve adjustment.
Have the ignition control module checked.
