trying to get my car back on the road, multiple codes thrown

[pbj24]

I have a '05 Aveo that has been sitting for a couple months now. The car is able to start and idle. Once you start to drive it though, the engine sounds rough and makes almost a fluttering/sputtering sound. Check engine light is on. It also is worth noting, that it took a minor hit on the front passenger side.

Anyways here are the codes,

P0300- random/multiple cylinder misfire

P0134-o2 sensor circuit, no activity detected (bank 1, sensor 1)

P1137-powertrain

P0137-o2 sensor circuit low voltage (bank 1, sensor 2)

P0303-cylinder 3 misfire detected

I am thinking about replacing both bank 1 sensors. Any DIYs, or diagrams i can use? Also best place to buy the sensors themselves?

Thank you, any help is appreciated thank you.

the sensors are right on the exhaust, one front and center on the exhaust manifold, and one centered the is easily accessed from the underside. It is super easy to do with an o2 socket, but you can use a wrench to put them on, taking them off is a little harder that way, but if your sure you have it right, the cut the wire and put a deep socket on it to get it off.

If you can wait, check eBay, or Rockauto. both typically have great prices. Buy a plug and play o2 sensor.
