I didn't look before I posted this thread :(

I am thinking of ways to improve gas mileage, and do you guys think re-installing my AIV will improve my fuel economy?

^^ LOL.... AGREED... CLOSE IT FAST...

Answer is "Probably not"... It adds unmetered air back into the exhaust steam which helps the CAT burn the exhaust gases better.
But, it enters the exhaust after the O2 sensor so the readings dont change..

Adding the AIV will help your emissions...
So, you will help Save the Environment~~~

They deleted it in 1994/5 (??) because it does almost nothing and malfunctions pretty reliably.

I don't think it draws metered air though. It draws air after the filter before the MAF.
