Started the Dart up on the weekend for the first time since the winter and noticed it just didn't sound right (Didn't sound the greatest when I put it away in the fall to be honest!). So I took my infra red temp guage and took some readings at the manifold. Atleast one cylinder is definitely not firing (The readings on the left side back 2 cylinders were much colder but the back left was considerably colder than the rest).
