P0353 code thrown. Not a plug wire?
So I check the new Taylor wire, and it is good, and seems to be on correctly (heard the "click" on both the plug side, and the coil side when installing it). Is there something else that could be throwing the code?
But what??
Assuming the plug is actually good (I'll check it soon), what else could it be?

Anyone have any ideas? I could really use some help on this one.

My problem ended up being a kinked wire leading from the PCM to the coil, or at least I think. I disconnected the wire harness to the coil, and then straightened out one of the wires from the harned and plugged it back in and it didn't throw the code and seemed to run a bit smoother. This could have also been that the connection wasn't all the way into the coil.
One more possibility this code can be is that the connection from the wire to the PCM itself can be bad.
I don't know that a fouled out plug can cause this problem, but a bad coil could lead to a bad plug I suppose.
P0353 is a bad ignition misfire in the number 3 cylinder. P0303 could be a general misfire not part of the ignition coil or wire on the number 3 cylinder.
Hopefully this helps out others who were having issues like mine.
Move the wire
Move the coil
if it moves, then you have found the problem.
Then check injector harness, injector etc.
Or do all of that to find out your PCM is dead..like me.
Change the plug, if no change, then look for the bad power/ground/signal wire for coil #3.
A fouled plug may be the result of something else going on, but not the cause.
Like I said before, any ignition cylinder code like P0353 should be from the wire, the coil, or the wires from your PCM to the coil. Or in a much more rare event, the PCM itself. Thats all this code can be.
I will state it one more time. This code is caused by one of these things or a combination of these things;
*A bad plug wire
*A bad coil
*A bad connection between the coil and the PCM to include a bad wire to the coil from the PCM
*A bad PCM
Thats it.
It is wise and easy to narrow most of these items simply by swapping plug wires and seeing if the same code comes back, or then swapping coil packs and seeing if again the same code with the same cylinder comes back. Its the wiring to the coil and the bad PCM that are harder to determine.
