Can some one help me I have the 2.2 lap I'm only getting 20 mpg I should be getting more the only thing I've done to it was I did the "air box mod "

 

how many miles on it? Is this recent or have you always got 20mpg? any check engine lights? tire pressure good? done anything to it recently? hauling around fat chicks? fat dudes?

 

did u try resetting the mpg in the DIC?

 

104250 miles no check engine lights i always reset my dic tires are all around 33 psi the only thing is different about the car is I'm running 195/65/15 when oem is 195/60/15

The only thing I've done to it Is the air box mod

 

the question is how your right foot is positioned. I average 28-30 with my normal driving. but get 42-45 (im not kidding either) on the highway when I'm cruising. but I've had my average drop down well below 20 because I'm driving like an idiot.
but in all honesty, a few millimeters of pressure on that throttle makes a world of difference on you mpg.

You got problems.

 

Now that's only in town driving not highway

But what can I do to fix this

 

well how much stop and go is it. because the average drops even when your sitting still. even in park or neutral (in my case)

Yes it does but it's a lot of stop and go for now it's my work car until I get another dd

 

You could be getting too much air. If your getting too much air it will **** with your gas mileage. The computers in the new cars are dipshits. You would have to get the computer reset if thats the case.

 

That would make sense onstar showed that I was throwing a code right after I did the air box mod but wasn't throwing the cel code was for the first o2 bank was reading lean

 

So many variables can affect MPG.
