I seafoamed the ranger
it was super easy/ i unhooked the brake booster line and got a cup and used half of the can of sf and let it suck it in, then the smoke started to pour out like crazy,then i shut it off and hooked the line back up and started it back up then i put the rest of the can into the gas tank and started it back up. It ran good but now its starting to missfire like a bastard. is it ok to change the plugs right away ?
