I pulled out the spark plugs out of my 3sgte and cylinder plugs 1-3 were in normal condition but the #4 cylinder plug was carbon fouled pretty badly. my ignition wires are fairly new and timing is actually set at about 15 degrees btdc so it should be running hotter than anything. The only thing left is to check compression...is there anything else i should check???
