    Sup everyone ! New to the board here...
    Ive got a question for all you guys!
    Here go's....
    ive got a 2000 honda civic si with cai, ctr headers, tanabe rm exhaust, no name high flow cat, and obd1 p28 conversion with a skunk2 ecu...

    My problem is when i start my car when its cold it sounds like its running on three cyclinders it eventualy goes away but it does it almost every time... I cleaned my fuel system and checked my spark plugs and it still does it.... ! Anyone know whats wrong?

    Thanks!
    Chris

    when a car is first started it tends to run rich
    the skunk2 P28 (or any other for that matter) runs VERY rich
    i would guess that your feeding WAY too much fuel to it when its cold

    you wouldnt happen to know your A/F ratio would you ?

    that really doesnt matter.... the "skunk2" program on your P28 runs in the area of 11:1 A/F ratio
    stock is somewhere around 14:1

    and thats when at full normal opperating temperature

    get the car to a dyno ... get something to adjust your A/F with (hondata or VAFC) and get it tuned properly
