I need HELP. Im chasing a problem that I cant find. I have a 98 GP GT. When its cold it runs great. But when warm it will buck and pop through the intake. I have tested the fuel pump and fuel regulator. Replaced the MAP, and tested the MAF. HELP what else could it be. When its warm it will cruse good but any exceleration is when it starts the bucking and poping. Please Help. Thanks David
