Knock Sensor?
I have a 2004 350Z with 145,000 miles and a diagnostic shows a code for a bad knock sensor. Can this affect fuel milege? I noticed that when I fill up I have used up 1/4 tank of gas in less than 30 miles and I drive it at 55mpg, if this is the case does anyone know of a reputable place in NJ were I can get it replaced?

If the sensor is dead (or more likely, the sub harness is bad), it will pull timing all the time by default. This is the fail safe for that sensor. I rarely see the actual sensor go bad. It's usually a problem in the sub harness. Replace both to be safe. To do the job right, you need the sensor, sub harness, plenum gaskets and manifold gaskets. I usually do the spark plugs while I'm there.
