Hmm, I guess I'm gonna be on the right lane all the time from now on
I had never seen such high mpg in 3 yrs of driving the car. But my happiness was short lived
... I got a check engine light after driving 314 miles a fillup and another 290miles (600 miles total) on the new o2 sensor. I guess the new o2 sensor isn't good although it seems to be more efficient than my older one. I'll check the codes tomorrow and let you know. I'll probably end up swapping the new o2 sensor back out for the old o2 sensor (that never gave me a CEL) and see if the slow driving does the trick for me.
I'm almost sure the old o2 sensor won't be efficient, so my question is...
What do you think of the
NTK 24300 from amazon? Is it something that you consider more reliable? (It is $175)
Thanks,
