injectors are very delicate and if you don't have the proper equipment or know-how, you could seriously screw them up. Your best bet is to take them to a shop and have them professionally cleaned and flow tested by a technician. __________________ 4 MORE YEARS BABY!!! | | | | | 06-07-2008, 04:24 AM | #3 | | Member Join Date: May 2008 Location: Easton, PA Posts: 90 | Nothing beats...

I don't know about cleaning the injectors, but I think these may help to improve fuel economy(I plan on eventually doing all these mods):
Rear window wiper delete, antenna delete, smaller more aerodynamic mirrors(m3 ones?), lowering the car 1-2 inches, max psi on original 185 15 inch tires, removing as much weight as you are willing to, blocking or taping off a large portion of the front grill and vents, fabricating full underbody panels, switching to a lower number rear diff, all sorts of custom aerodynamic pieces
I am sure there are plenty others, hopefully with gas so expensive people will start to experiment more and discover new fuel efficient mods, driving style also has a large impact on fuel economy. | | | | | 06-07-2008, 09:41 AM | #8 | | Senior Member Join Date: May 2007 Location: LA, Bellflower, CA Posts: 3,613 |

I see people saying they get 37mpg, and I just don't know how that is possible. I would almost suspect a bad OBC calibration if the OBC is reporting that high of mileage. I get around 27-29mpg with recently cleaned/flow tested injectors.. | | | | | 06-07-2008, 07:11 PM | #10 | | Member Join Date: Mar 2008 Location: MA Posts: 76 |

yeah i know what you mean. im barely starting to get like 23-25mpg at the most. ever since i change the valve gaskets and cleaned up the spark plugs its been a bit better. but im still stumped on how to get more than 25mpg to 30 mpg like others are getting... i would like to get the same if possible.
anyone know of what we can do to improve the mileage? __________________

wheels are a huge part of fuel economy.
but when was the last time your o2 sensors were replaced? __________________

I was getting 34.6 to 35.1 MPG on my 45mile commute to work on stock 15" wheels. Put on new Kosei 16" rims and Dunlop Direzzi's...mileage is dropping back to 34.1 MPG..minor but the larger wheel makes a difference.
Remove the spare tire too? ..if ya feel lucky. | | | | | |
