Clean it IF it's a K&N. If not, replace it with a K&N.

As for a valve adjustment, NO, I don't want to take responsibility for anyone doing this job wrong. It's not difficult to do, but the procedure is exact and specific. The FIRST thing you should do before attempting to work on your own engine is buy (at least) a HAYNES manual for about $15.



By following the step-by-step instructions listed in that manual, there is little chance you'll get it wrong, and they've already done a much better job outlining the process than I can. I wouldn't trust someone's DIY over a manual for a job like that.

 

lol Jafro.. u da man! haha nice manual!

 

i usually get 300-345 miles per tank in my 99 Si with 102k on it...

 

It's actually a real book from a British press. MachV sells it. I thought it was pretty funny, too.

 

hey I will get you a diy as soon as I can. I am working on one for 5th gens right now. I think it is the same process as the 6th gens so I will let you know

 

hi,there,can you tell me where to buy NGK blue wires for a SOHC Dseries engine,because i wanna to put one set of those but i dont know where to buy it and which the referençe for my car,thanks

 

I know that I'm probably late, but a bad oxygen sensor will make your car run rich, and in return get worse gas mileage.

 

however a bad oxygen sensor will also "usually" throw a code
