Bad Gas Mileage, what to look for in datalog?

[GTJake]

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,
Jake

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

Ever notice how the greater the opening

The greater the fun

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.
