Re: EF Gas Mileage

You all must drive like saints if you're getting that kind of mileage. I get between 26-30 like OP in a 90 std hatch.

Re: EF Gas Mileage

I fixed my idle problem with a easy 30min tops fix
https://honda-tech.com/forums/honda-crx-ef-civic-1988-1991-3/how-clean-iacv-dpfi-idling-problem-2443124/

I was able to research this out on the forum and it is proven helpful!

when i took it apart I didnt find a wood chip but there was alot of dirt in it.
I just used carb cleaner to get it out, wear gloves it burns lol, highly recommend!!!!!!!!
and tires are still at 35psi.

Re: EF Gas Mileage

Quick review of MPG tips

1) New 02 Sensor
2) Cap, Rotor, Plugs, Wires
3) Tire Inflation
4) Motor and Trans oil
5) **New/rebuilt Distributor
6) Measure properly. Fill up at your favorite station, at your favorite PUMP. Zero out your trip odometer. Drive around. Go back to same station, SAME PUMP. Fill car. Note miles, and how much gas it took. Do math (Divide the two #s). Do same test 2 more times (same station, same pump, zero out each time).

** I've heard this, is this true?

Wheels and tires make a difference... weight, rolling resistance and all that.
