so i was having some random missfire codes, shitty gas milage, random hickups and stumbling and finally decided to pull my plugs and see wtf is up and wouldnt you know 2 of them are fouled...

they are ngk tr 55s and this is the 3rd and 4th plug ive had foul on me....

wtf is up should i swtich brands of spark plugs and see if that happens to them too? if so wut should i switch to?

thanks
