I am not sure if its anything or not but I started my car up and let it idle for a few minutes and drove home about 3/10 of a mile and my car was popping pretty bad. I didnt have any timer to really check it out I was in desperate need of Supper. I am going to take it back out shortly to see if its still doing it. If it is my guess is a fouled Plug. I only have 12k miles on the car. What do you guys think?
