Hey guys!

I have a 98civic, a sedan.. D16Y7, i have change a lot of things on my engine, to save gas because it has been doing like 25Mi per galon, and it is killing me! I have change the oxygen sensor like 2 weeks ago, i use the Denso that it is like the oem one, no change at all.. I change the spark ligth, im using the Ngk one, that is showed on the catalog for honda, still nothing, can u guys give me some ideas of what else can be the problem?? I will really apreciated that!

Pd: sorry for my english, im from Nicaragua and i guess that i hve a lot of misspelings xD

 

check your air filter I was getting about that until I realized I have never once changed it in 2 years of driving that and do the fuel filter and possibly clean the throttle body out

 

How can i clean the throttle body?? Is there any specific product to use or something?
