There are several problems starting with code P0301cylinder one misfire that showed using AutoZone code reader. These messages are seen on the OBD: Left rear door ajar, low oil pressure and Oil life at 0%. Also, the buttons for the OBD don't work. I've checked the fuses and they're fine. I have pics of other codes that have come up when I used a friend's more expensive code reader. I just replaced the power steering pump last week. It was a real hassle getting to it, but I got it done. I've replaced three of the six ignition coils and plugs and I'm not sure how to get to the other three. There are a lot of things in the way.

This sounds like two different problems, please start a new question for the "Left rear door ajar, low oil pressure and Oil life at 0%. Also, the buttons for the OBD don't work." We will fix the p0301 code in this thread, I would start by installing new spark plugs and service the throttle bore. These guides can help us. I have also included the instructions on how to replace the spark plugs on your car in the diagrams below. You can replace the ignition coils at the same time.

Some of the spark plugs are tough, try to undo the engine mounts and rock the engine forward in the car. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
