Re: Low Miliage

Any idea how much the O2 sensors cost? My friend is gonna put 6 new spark plugs.

Just a couple notes,

I did 100 or so highway with power drive and got 16mpg, w/ subs on.
Then I did a 100 or so highway miles, and got 13mpg without power drive.
And then today I did 100 or so highway w/ out subs and with power drive on, and got 16mpg.

So I think the subs don't make any difference.

However power drive added at least 1-2mpg. Interesting.

Ill find out if the spark plugs do the job on wensday when I make another highway drive.
