Problem with Oxygen sensor. Bank 1 sensor 2

[Jono2212]

Hi people , I have a problem with my Saxo 1.4 Furio regarding the oxygen sensor bank 1 sensor 2. The error code I am getting when i plug in the OBD Diagnostics is P0136. This recently has started another problem and i get a misfire and then a code P0300. I have had both sensor 1 and sensor 2 changed and reset the ECU but however the problem persists. I have noticed though, it seems that this only happens when it is damp or cold ? any ideas where i can look at next ?

Btw , i am not sure if the the P0136 is affecting the P0300 as the misfire "Could" be due to a faulty sensor ?

Coilpack i would say mine done the same but i left it just let it warm up for a min and was fine.

[Jono2212]

Could the coilpack cause the problem with the 02 sensor then ?

it sure can if its misfiring then it'll fuck with the cat and how well it works wich will make the 2nd sensor read that there is a problem with the cat.

thanks guys , i was about to change the coil pack but i decided to try a little something first. My battery had discharged 3 times and it was getting a little juddery. I went and bought a new battery, reset the code and funnily enough it hasnt done this problem since i changed the battery... Think the power was that low to knacker up the oxygen sensor to cause a missfire ?
