    I'm getting horrible gas mileage (~12). What should I look for in my data logs? Also, I got a check engine light and it went away. Any way to check to see what codes it tripped using the tweecer?

    Thanks,

    I took a look and for some reason it says my TPS voltage is at like .80??? Could that be it?

    I was wondering the same thing with my car. I was getting nasty mileage and couldn't figure it out. I'd like to see if anyone has some good input.

    I got a sneaky feeling if all of us loaded the TPS column in Excell for an average of values

    The % of opening would be greater than we suspect :eek: :rlaugh:

    Ever notice how the greater the opening

    The greater the fun :D

    But my TPS voltage has always beeing around .98 and now it's stays at .80, rock steady. I haven't checked it with a voltmeter yet to be sure, but it sure seems wierd to me.
