Ignition coil problem, misfire code.

[gokaipyro]

I have no idea what's going on, I have a misfire code in cyl 3. Looked at the spark plug in 3 has normal wear I switch the plugs from 1234 to 3214. Still misfire in cyl 3, so the injectors are fine as well. So lastly I get a new ignition coil and the car doesn't start, it tries to start but doesn't. So I put the old coil back in and the car starts but still misfiring. I've no idea what to check next.

Maybe the new ignition pack is bad?

This is the second coil pack I bought. That was why I bought another because I thought the other one was bad when I ordered it.

oh wow.. plugs bad? Maybe the crank position sensor ?

If it was the ckp, why would the old ignition coil work but the new ones wouldn't.

Wondering (and I can't see why it would be) if there's a part number on your old one, does it correspond with the one you bought? I wonder if one from the dealer (more expensive yes) would be a solution?

Mine threw a P0300 and they diagnosed cracked cylinder. 2012 1.8 at 130k miles. Good luck.
