Hi there!

Needing some help with my car... -- 00 Civic Si - pretty much stock w/ an aem cai.

So about a week ago, I was driving along and noticed that my car seemed to be much quieter than normal when I was supposed to be in Vtec. Didn't think too much about it. So 3 days later, I finally had a day off so I washed my car and cleaned out my K&N filter to my intake as well. Later that night when I was driving on the freeway, my check engine light when on. Took it to Autozone the next day to see what codes the computer was throwing out and it said "P1259 - Fuel Air Metering" was what was wrong.

Help with this? What part is messed up? a sensor? Think it'll be an easy thing to replace??

Any and all help is very much appreciated!

 

i would check your oil/oil pressure switch, valve solenoid, or a loose connection

check the conections on the sensors on the intake manifold as well as the one on the intake arm.
