If anyone out there would like to know what i replaced on my 87 to get it running like a screaming banshee here goes; fuel filter, air filter,fuel pump,main fuel line,carb-bank,spark plugs,and lots of 91 octane! Now that fuel prices are a little lower its worth it! It runs good on 87 too! i also poured a can of fuel system cleaner in there...the whole can..if its running decent it shouldn´t hurt it!
