So my service engine soon light came on and I took it to Auto Zone to have the codes pulled. He said it was a misfire. So i changed all the plugs and it went away for about a week. Now its back. I took it back t Auto Zone and actually wrote down the codes. If anybody could look these up I would greatly appreciate it.:SNSign:

Yea I'm a idiot i didn't post the codes. I'm watching the game.
The codes are PO316 and PO307

What year car is it? Any recent mods that may be related?

I would specifically go over cylinder 7's plug, COP (or plug wire) looking for any signs of what might be happening. I'd also check #7's injector wiring harness for damage.
