Hi Everyone, I've tried to search for a remedy for my problem but didn't. I need the community's help. When I started to get the p0303 error code I switched the coil pack from cylinder 3 to cylinder 1. Then cylinder 1 started to misfire. So I went and got a new coil pack and spark plug set (NGK). Replaced all spark plugs and coil pack in Cylinder 1 bc it had the bad coil pack. Everything seemed fine but after a few miles, 15 miles or so, I am getting P0303 again. My conclusion is something other than spark plug gapping is causing cylinder 3 coil pack to die. Please help me find this ghost living in cylinder 3.
