First of all it idles very rough and anywhere from 800-1500 rpm sometimes. Upon heavy excelleration, its very sluggish. Several items have been checked and or replaced: MAF sensor, fuel pressure regulator, fuel pump, plugs and wires, and lastly cats were checked. I am thinking its probably an injector. I am stumped...HELP....

Clean out the idle air control valve and EGR valve/Test the Throttle position sensor and try running an injection cleaner
