It's idling very roughly, almost no power, and when it does get power it's just a surge and barely goes at all. I got it to the near by auto parts store and got the code ran and 9 came up. I'm just trying to figure out what needs to be replaced to fix it. It happened suddenly with no symptoms that anything was going wrong. Here's the list:
1. P0125 - Insufficient Coolant Temp. For Closed Loop Fuel Control
2. P0171 - System too Lean (Bank 1)
3. P0172 - System too Rich (Bank 1)
4. P0300 - Random/Multiple Cylinder Misfires Detected
5. P1133 - Air/Fuel Ratio Sensor Circuit Malfunction (Bank 1 Sensor 1)
6. P1135 - Air/Fuel Ratio Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
7. P1305 Ignition Circuit Malfunction (Bank 2 No 2)
8.P1315 Ignition Circuit Malfunction (Bank 4 No 4)
9. P1325 Ignition Circuit Malfunction (Bank 6 No 6)
If anyone can help it would be greatly appreciated, I can change bout any part, but figuring out which one is where I have a hard time.

Please reset all codes and re-read on the first onset of CEL.

How likely is the it that the Air/Fuel Ratio Sensor (Bank 1 Sensor 1) is the cluprit for all these codes? Seems like if that's wasn't reading correctly it could effect the ignition system and and mess with the other stuff?

just buy a cheap scanner and reset. Or just disconnect battery for about 1/2 hr
