I am having the same problem. I took it to get the engine read and it was also the 3rd cylinder that I am having the misfire on. I can not find any videos on how to take the manifold off to change the coil pack, but I DO NOT want to take it to a local repair because the ones around here are not ones to trust to repair it properly and to be honest about it. I live in a small town. Did you find any solutions?
