HELP! Starting Prblems

[Cwest Si]

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 ?

nope but ive got a fuel gauge and a b&m fuel regulator under my hood. It's at stock settings....

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
