If anyone could help me i would really appreciate it...Im here in california trying to get smog check and got a OBD Reading

Shows all 4 cylinders are misfiring

and my obd2 sensor is out....

I believe the misfiring is due to spark plugs? what do you think

and also it says sensor two....would that be the one on the cat and if so does anyone know where to get one for cheap....

This is the reason my checkengine light is on....

Any suggestions? THANK YOU

 

What codes are you getting?

 

you know what i dont have the codes in front of me but i know for the sensor it was 0141...and the misfiring im not 100% sure right now but they were all in order from cylinder 1-4....

 

here are cylinder coads....
