dude i don't think any injector cleaner is goin to help you dude......one because the cleaner requires you to app. with a full tank which delutes it to nothing second the fuel is running through to fast to dislove anything.......i think you should just pull em off and check the screens on them. also double check you timing esp. if it smells like its burning rich or lean do a complete list of things.....and do a tear down if that don't work i don't know what will.....but your best bet is take the injectors off its only a couple of 10mm bolts but if i had to say the best dissolving cleaner...4(carbon)is z-max but the shit is kinda expensive....check it out for yourself go to autozone
