So far I've changed out all plugs and coil packs for cylinders 4 and 8 because I retrieved codes P0304 and P0308 and P1000. My truck continues to throw P0304. I've also used an EXPENSIVE injector cleaner. What else can I do, Could you please help?
I have an 07 Sport Trac with 4.6 with #4 cylinder misfire. on 2007 Ford Explorer Sport Trac

maybe your injectors are starting to fail, try switching injectors with others.

I went out last night and picked up a multimeter to test my injectors. Can anyone advise me on what the normal resistance should be for my injectors.
