I have a 1994 Pont. Firebird Formula 5.7L LT1. After the engine warms up it will load up and cut out under acceleration. When it's cold it runs great. I've replaced the plugs and plug wires, and the EGR valve. What might the problem be? Could the plug wire be a bad set and need to be replaced again? Has anyone else had this problem, Please help.
