Question P0353 code thrown. Not a plug wire?

So I get the SES light on in my 98 Formula in my sig, and it reads; P0353, which should mean there is a wire issue on the #3 cylinder (if I am correct in reading the code).

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?

How do I do that? I had aftermarket wires on before, and it threw the code then. I changed the wires thinking that might do it, but after the new wires were in, and the code still was popping up, I figured it had to be something else.

But what??

you would need an ohm meter but it sounds like the wire is good if you had that problem before

I am confident it is not the wire. Could it be the coil? Or the plug?

I guess that will be the next step. But if the plug was fouled, I don't see how it would send the P0353 code.

Assuming the plug is actually good (I'll check it soon), what else could it be?

Well, I am baffled. I know the plug wire is good. I thought I would swap the #3 cylinder coil with the #1 cylinder coil to see if it was the coil. I did that, and it threw the same P0353 code again. I am really confused on what it could be at this point.

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

I'm in the same damn boat, throwing the same code. I changed the plugs and the #5 was full of soot. I changed the plug and still the same problem!

Usually the P0353 means there is a bad plug wire or a plug wire that is not on correctly. The next step I would take is change the coil from the bad cylinder with another cylinder that is good. This will help eliminate or track down if the problem is actually a bad coil.

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.

Change the plug
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.

He's already determined it's not the wire and not the coil.

Change the plug, if no change, then look for the bad power/ground/signal wire for coil #3.

It shouldn't set off a misfire code if your plug is bad. (Meaning the P0353)

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.

Well as far as my situation is concerned, I changed the plugs and wires twice! I got my injectors cleaned and flow tested. I installed everything back on and im still having the same problem! The last thing that can only be is a bad coil! So I will be picking one up at Speedinc in the morning and see what the results will be THIS time.

^ Have you not read what has been posted? A plug will not cause the problem, and to my knowledge, neither will a bad injector.

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.
