The first one is O2 sensor, Bank one, sensor one
The second is Knock sensor, bank one, sensor one.
The third one is P1105 which was not in the book.

The fourth one and the one that worries me the most was P0300 which I believe is multiple cylinder misfire which I'm wondering is why I'm hesitating and idling erratically.
Can this be the ignition coils which need replacing?

 

1st step would be replace o2 sensor.

 

the 1105 and the 1302 code correlate.. i have the 1302 code.. and its pissing me off.. its that very general code saying you have issues with your map/baro valves and such.. also since you threw a knock sensor code.. it could be related to your 1105 code.. you have this thing called a "boost sensor" with your stock intake.. that may need to be replaced too..

 

Did you know that 97.3% of bosch 02 sensors that people change out are fine? It is just doing its job of telling the car there is a rich or lean condition. He did not even say what code for o2, there is like 45 codes related to o2's.

 

Hey man, I have a universal o2 If you are interested. LMK

Check this solution for code P1105:

P0300 would lead me to believe one of your coil packs is going and you need to start the engine and one by one disconnoect the coil pack power source and listen if the motor changes sound significantly. If it does not, you will find your coil that is causing said misfire.

As far as the KS goes, It may have been tripped by the misfire code

 

I was told the P1105 code could be a hose not connected properly somewhere on your car.

 

The O2 code I think was P0135. Its been on for almost a year....... All those other codes weren't.
I just changed the firewall side coil packs. I'll order the radiator side this week and change them too.
I guess I'll look into the knock sensor too

 

replace ur shiznit then check codes again
