Has any one experienced this before? Car has been driving kind of sluggish and could were all replaced as well as spark plugs. After the install instant misfire cylinder 1. Moved coil in cylinder 1 to different cylinder, still cylinder 1 misfire. Baffled, I googled, googled, and prayed to god that I wouldn't need to replace my injectors yet. Figured I might've done something wrong, switched cylinder 1 and 2 spark plugs. It folowed, luckily I kept the old spark plugs. Replaced it with an old one, and works flawlessly. I now have all new plugs but cylinder 1. Hopefully dealership replaces the 1 plug I bought that is faulty?

Haven't experienced it myself but I've read ALOT of people buying DOA plugs. They always recommend buying 7 for that very reason. If you bought it from the dealership, i dont know why they wouldn't give you an exchange.

Did you happen to check the gap on the new plug? Sometimes they get banged around during install and it messes up the gap. That is the only thing I can think of as a faulty spark plug itself is rare.
