Ok, i have a '99 civic ex with a '00 B18b swap.....it all started out with a bad idle problem... i cleaned out the TB and all sensors on the TB;i.e. fast idle control valve...right now my idle is not a big *** issue to me right now......when i 1st start my car in the morning everything ok... i'll drive to work or where ever and turn it off. come back maybe 30minutes later or less and start it back it up....now when i do start it up it wil lstart but jsut idle down and stall-out....... could it be vaccum leak(s), possibly a fuel filter/pump.....injectors (im using jdm GSR right now)....... any ideas or things to look for??? im shootin'blanks and its getting annoying, thanks in advance....

are you throwing any codes?

check your IAC valve, check your coolant level, is it rough at idle? If so you could have a bad injector or a sticking injector. hmmmmm..... all the basic stuff idle screw position, vacuum leaks, wiring

im not throwing any cels...except every now and then i'll throw one which i suspect is a random misfire due to the plugs and wires im using..(ITR plugs/wires w'roughly 48k on 'em)......

its not so much rough at an idle as more that is surges sometimes...my wiring should all be kosher as it is all plug and play (obd2b d16y8 harness)... i am running a bypass on the coolant lines to the TB however;but i know people that have also done this and do not hae any problems from it.... im gonna run through my vaccum lines again and see if i find anything diff.

thanks gt30typer
