I had a oil change about a month ago, mobil 1.. I really don't drive the car much just about 50 miles a week. I changed the coils because I had a bad one and I had a gift card to jegs and figured what the hell I'll give them a shot. The coils have about 500 miles tops on them. No cel lights or anything, this problem just started a few days ago. I love the car but damn every month its always something!!
