Hi I have replaced the sparkplugs,wires, coilpack, egr valve, fuel filter and an o2sensor, and my van runs fine at an idle but when I press the gas it falls on it's face, and or boggs out, and will back fire through the intake, I've also un hooked the exhaust pipe to see if the catalatic converter was plugged still same, please help!
