Sweet new ride... buuuut

Just got a civic Si off a friend today, strut bars, momo wheel, 4pt harness... not bad. My fav part is the B16 he had packed under the hood. He also tossed me a turbo, intercooler, and blowoff he was gonna put on there b4 he decided to sell it... BUT my one single prob with the car is when I pop outta gear, like comin up to light or somethin, my idle drops to dam near 0 like it's gonna die, then kicks back up to a little over 5. It could just be I need to adjust the idle a bit, but i still wanted to get some more input though.

check vacume lines and check the thruttle cable and the TPS

leaking vac hose?

LOL, you beat me too it good timing

Spark plugs?

or does it have a light weight flywheel? They can do that also...

unless it has a super lightwieght flywheel i dont think its gonna do that. i have a 9.5 lb flywheel on my b16 and it doesnt mess with the idle at all. mess around with your idle screw and maybe replace your TB. my idle was doing the same thing, and i just set my idle screw higher, and now it has a tiny but of a high idle, but i can deal with it, and i think its due to my TB cable cause i can pull up on the pedal and the idle goes to normal.

my 12 lber actually used to do that though, maybe it was just flywheel/engine combo...
