O2 sensor cleaning - mistake? PLEASE HELP
Kind of wrong forum but need help.
2010 Infiniti G37x I installed a set of Megan test pipe DP's - 1st mistake but cat was broken and rattling and these were CHEAP. Throws a CEL but runs fine but rich. Decided to get a set of 90 degree O2 sensor extensions to help turn off CEL and return to normal non-rich condition. Decided to clean the sensors with carb cleaner like the internet says - 2nd mistake, I know to only change one thing at a time but ran rich like this for 9 months and figured they were too dirty. Dried them with a small butane torch for 1 min. Installed them with 90 degree extensions. Now have P0301 code/misfire cyl 1. Tested the ohms and got 3-5 Can't get voltages while heating them, don't if I am doing it right, I hate electronics BTW. Swapped the sensors cross car - no change Removed the 90 deg extensions - no change Am I looking at getting another set of O2 sensors or will they eventually dry out? FML |

O2 sensors are easily damaged... i had low mileage sensors go bad because i had to move the car with only headers installed due to a incoming hurricane. The codes were specific to O2 sensors tho.
If those codes are O2 specific, i would try new sensors. Also i dont know too much about your car model and running catless DPs. Extenders might not work. Do they make O2 sims to trick the computer? I would go with that if possible... |
Appreciate
