I heard this from a ranger site about whether the oil on a k&n filter contaminating the MAF. While i doubt this, a contaminated MAF could be a problem for MPG. I have the o so common drop in MPG that seems to plague the versa and was wondering if anyone has tried to clean the sensor yet.
Also to those who have replaced the Oxygen sensor, why? Is this an attempt to again fix the MPG problem or was a code thrown? If a code was thrown, does this trip the CEL light or does it take more than just the O2 sensor being out of whack?
thanks for the o2 heads up. as to the k&n, i agree with you if a large amount of oil were to adhere to the MAF then it would screw things up. But if relatively small amounts of oil contaminated the MAF, that would be enough to affect the performance of the sensor without setting off the knock sensors from running the engine lean.
another way to diagnose this is a question. Do any of yall who have mpg drops have the k&n panels or is this just a universal thing?
Im not intending to put this up but just in addition. of course you need to run an injector cleaner to make it easier. On the other hand, you can use a scanner to figure out what's really behind those sensors. Got replaced two sensors and running the cleaner afterward.
