po351 code changed coil twice
this is a continuation from (sudden bad miss) the obd is reading again and I was told the pcm turns the air off with bad misfire so I am concentrating on trying to find the cause of misfire.
I have replaced the coil twice with same code and miss showing. also replaced the spark plug. have inspected wires etc. checked firing with noid light. had steady flash with koer.
not sure where to go next. could this be the pcm anyway?
any ideas appreciated.

0301 code is the COP....... 0351 is the supply power TO the COP.. look at the electric plug, broken wire, bare wire, kinked wire... I had to replace a plug and 6 inches of wire on a 2006 4.6 motor due to same code.
