P1300 is Random Misfire or Random Misfire likely due to low fuel
The rest relate to Bank 1 oxygen sensor failure and disconnection.
I would guess you have a disconnected or damaged Oxygen sensor wiring harness causing a lean miss on several cylinders.

p0155 means O2 sensor, still looking for p1300 cant find it.
P1300 is a Boost Calibration Fault. For more info, you'll have to talk to yourmechanic.(from this source) http://www.troublecodes.net/OBD2/Pcodes.shtml
You may need a new Random Misfire Solenoid P1300!
To fix OBD code P1300, which often relates to an issue with the ignition system or misfire detection, start by checking the spark plugs and ignition coils for wear or damage. Inspect the wiring and connectors for any signs of corrosion or disconnection. If these components are in good condition, use a diagnostic scanner to check for other related codes, which may help pinpoint the issue further. After addressing any identified problems, clear the code and perform a test drive to ensure it doesn't return.
: according to my code scanner book, P1300 is GM-specific for "Ignition Coil #1 Primary Feedback Circuit". P1305 is for coil#2, P1310 for coil #3, etc. : I'm getting a P1301 right now, along with a P0301, cyl#1 misfire. So I'm guessing that the P1301 is also related to coil/misfire issues and am going to replace that coil and see if it helps.
