"I replaced 4 original spark plugs with E3s. Car ran well for 57 miles then picked up a misfire. I checked everything but the spark plugs trying to figure out what was wrong. I had changed plug wires and coil pack at the same time. After exhausting all else I pulled the brand new plugs only to discover the #4 plug was not firing properly. Replaced it and the car is fine. All plugs will be replaced now! I have never had a brand new plug short out in my 45 years of working on my own cars." posted by: Jim on October 3, 2011
