I had drive around 700 miles in two days. It was running great. Got off the highway, at a light it started idling rough, then check engine light. Code reader showed 1 & 8 misfire. I was confident it was just the coils, but wanted to pull the plugs to look, figured I would put new ol while at it. Both plugs were pitted. Glad I did buy some…. I’m going to change the other 8 this weekend. Now I’m thinking of carrying around a new coil..
