2008 Running rough, down on power

I have an '08 Liberty with 51K miles, about 2 weeks ago it started running rough on start-up and sluggish when accelerating. Originally thought I had bad fuel since the problems started shortly after a fill-up. With the check engine light on I checked the codes with P0300, and P0132 coming back. I replaced all the spark plugs thinking that might be the problem.

When the symptoms persisted I checked the codes again with P0301 now added to the previous. Today I replaced the #1 coil hoping to fix the problem which it didn't. Checked the codes again got P2302.

My question is where should I look now to remedy this problem?

The second code is also attached to the coil.

I would start with swapping coil packs from another cylinder and make sure you pull the plug and check or replace it.

If you have the same problems after clearing the codes you will have to start testing wiring from the coil to the PCM.
