However; it's a stark difference from 37mpg that I originally had involving a cracked Civic EX exhaust manifold, as provided from the original owner.


But like I was saying, from the suggestions and advice from a lot of experience owners, I have performed the following maintenance listed below and would like to know what else I should do to achieve the 50mpg mark:

-Complete tune-up consisting of OEM spark plugs, wires, cap, rotor and fuel & air filter (i.e. all from Majestic Honda) I even indexed the spark plugs.

-Thorough cleaning of the IACV and EGR valve, along with the channels.
-Thorough cleaning of the throttle body.
-Readjusted the base idle to 650 RPM's
-Readjusted the ignition timing toTDC
-Installed a complete OEM exhaust system with a used VX exhaust manifold, new catalytic converter from Majestic Honda, down pipe, center pipe & muffler (No practical aftermarket alternatives available for the CAT).
-New OEM L1H1 5-wire 02 sensor from EBay.

Thank you.

Have you seen basjoos' AeroCivic?
It's essentially a streamlined version of your VX,which can remain in lean-burn well up the velocity curve.With Cd 0.17 the engine doesn't have a lot of work to do.
