F 150Cobra
"Wild HoRsE" Got Torque?
spark plugs was changed not more that 10 K miles ago..
the set before that lasted 15K miles..
all of the sparkplugs stays in good condicion exept!! the ones from cylinder 4and 8 the ones closest to the firewall.. i was told that the PCV valve is bad but it was replaced 5 K ago... the 4 and 8 cylinder spark plugs comes out OILY! and i guess the oil wont let it spark correctly
another thing... how to chek while engine running wich plug is bad? remove the wire at the dist. cap one by one and see wich one is it? or remove it by the plug? wich way wont give you a shock ? lol
i just want to know wich one is bad and replace it with one from the old set wich is good and see if it corects the problem.. dont worry its the same type sparkplug the old and the current set they dont have more than 20K on them
they are motorcraft platinuims
