I noticed a huge diffrence in fuel econemy when i pulled my air adjustment screw (or whatever its called) and cleaned it all out on my intake.. The screw was all gummed up and so were all the pasagges and hole where the screw went in... Spent about 45 min cleaning that out... But i have noticed the increase in fuel econemy. I travel the same distance everyday back and forth to work and right now im about 1/4 tank higher than im usually at at this time...
