Hello every one I'm a em1 owner been a Honda fan since Moby dick was a sardine but have little knowing I'm hondas....from Texas ...and I already have a problem with my si . I just bought it about 6 months ago and I'm getting poor gas milage...I was told it had a gsr tranny could this be my problem or the ecu..?? "Help"

 

Welcome to Honda-Tech. Glad to have you on-board.

I like your analogy there lol! I would start off with some spark plug wires and plugs first. Then move onto the air filter and fuel filter.

 

Lol...yea see the thing is I already did that...and still getting poor gas milage...I'm wondering if there was a b18 on the car before I bought it...would the ecu have any thing to do with it..?
