2003 expedition cop problem
Ok. This weekend I tackled changing out the COPs and plugs on my expedition. 230k miles and was running strong. I keep getting error code PO351 which is cylinder 1. I just put another new cop and plug on that one to see if either one was the problem, and I still get the CEL and the PO351. What else can it be besides the cop or the plug. BTW. My ac doesnt blow cold either since I finished. What on earth did I do to my truck? HELP

Code P0351 means that the computer keeps losing connection to the COP on cylinder #1. Start by inspecting the 2-wire plug going to the COP to see if there is any corrosion, breakage, or bad connections.
