My car is getting shitty mileage, 17 mpg city, 24 highway, so I did basic tune up. Well, more than basic;

changed plugs, set gaps to 1.1
changed wires
changed fuel filter
changed air filter
changed pcv
changed o2 sensor
changed distributor cap

Now, im still getting the same shitty mileage. My two last resorts are retarding timing (engine pings with regular fuel) and replacing distributor rotor. I can't figure out how to remove the old rotor and have no idea how to adjust timing, any of you wanna give me some instructions?

 

Your ECU can also affect gas milage, but i would just take it to a honda pro and have them check it out.

 

Sorry OFF Topic, but what color is your car?

Laguna Seca Blue?

As for mileage... you could also make sure your wheels are spinning freely (bearings not shot). Check tire pressure... amongst other small things that affect MPG.

 

Its P-shopped ............it is origanally OEM red

 

no, its black....


actually i believe at least one rear wheel is harder to turn than the other.... im not sure about front wheels, but one of the rear wheels, i have to apply some force to turn it. dies that mean the bearing is shot? or maybe it just needs some lube? maybe its the brake not adjusted properly?

 

Nice job, you fooled me!

About the color of the car, I was reffering to 165EJ1

If it's bearing related, then you would probably be hearing some whining noise from the wheel hub.

It could also be one or some of your brakes catching that is dragging.

 

probably the brakes, i dont hear any noise. but the effort to turn it isnt great, i dont think it would result in much mileage loss
