I get about 180 miles per tank, I have a Civic 89 LX D15B2 Auto tranny.

What can I do to better this?

O2 Sensor? Fuel Filter? Dirty Injectors?

Can I clean the injectors myself? I don't have the money to send them to a cleaning shop, any tips on this? If not, how much do the 2 new injectors cost? (DPFI), doesnt have to be OEM honda parts.

Also, my car seems to miss alot when it's cold at idle, what gives?

 

i just had my injectors cleaned by a mechanic. i think they hooked some fancy machine up to the fuel rail. its alot better than that stuff you buy at walley world. i cost me about $60 to have it done.

 

I get about that much too. You have any CELs on? maybe change you ro2 sensor or fuel filter.

 

nope no CEL, but still lazy fuel economy

about how much do the 2 fuel injectors cost? not that much i guess?

thats like 15 mpg :S

 

fuel filter air filter injectors algienment you mash gas non stop? check for codes.

 

As far as fuel injector cleaner, get something good like Techron Fuel System Cleaner or Seafoam.

 

Air filter
fuel filter
thinner oil
higher tire pressure
remove unnessary weight
cruising at 55-70 mph only on highways
being smooth on the accelerator
new O2 sensor
