Well...I go for my emissions test tomorrow and am having a major internal debate as to whether I should replace my O2 Sensor before I go or not...
For the past few weeks I've been getting both codes 44 and 45. Mostly
- And like I've said before, I have a A/F Gauge installed and today it did the thing again where the O2 will stick in the "RICH" and just not move...I was idling for about 7-8 minutes and it didn't move at all...
I had the O2 Sensor replaced in September of 2002. It's funny because when I had the emissions test done in July of 2002, I passed, and the guy said I should replace my O2 because of a slightly higher than "normal" readings...so I went ahead and replaced it to see if my mileage would increase...and now, 2 years later...about to go for another emissions test, and this time the damn O2 sensor is acting-up again!!
Today I did a few maitenance things like taking off the throttle body and giving it a good cleaning...as well as the IAC...and I cleaned and re-oiled my K&N Air Filter(which was quite dirty)...and I erased the ECM's memory and did an idle re-learn...
After all of that...NOTHING has changed!!
Anyways...I've heard that O2 Sensors usually only last about a year so I guess I must be due for another one, right?
THANKS!:)
