Stop pulling wires and possibly damaging them,you can buy a test tool that clips on the plug wire and shows if it is good.The problem keeps on cyl6,so attack it there.look for frayed wires in the maf circuit and your wiring harness,i.e. any baked wires in the intake /manifold area.then get a shop stethoscope(cheap at autozone)and listen to the injector on cyl 6,can you hear it buzzing and clicking,that is how it sounds if operating correctly.Then run some techron fuel injector thru the tank as instructed,but do it at 1/4 tank and then add a few gallons to get to 1/2 tank and mix up the additive with the fuel.Why did you replace the maf if it had no code for a bad maf?Do you have the old one?Where did you get the new one,and who made it?
