idle at 2k
 

b16a1 with 99 si intake manifold and STR TB on a 90 hb si

ok how do the lines on the iacv suppost to be hooked up....this is how its hooked up right now....coolant lines from the thermostat housing then i bypass that line to the left inlet on the iacv ..i think its supposrt to go on the TB then to the iacv, but since i have a STR TB it aint got a cold start..so then i jess ran it straight to the iacv then the right inlet of the iacv is hooked up to the block to where the coolant runs on the lower radiator hose..!!is that the right way...

is this the cause of high idle at 2k...moring starts are cool its at 900-1k..then as the motor gets warm then it goes to 2k and stays there..what could it be https://honda-tech.com/forums/images...s/halfstar.gif

Re: idle at 2k (90hbvtec)
 

left side of the iavc comes from the tb (i bypassed mines so its coming from the top part of the motor) ...right side goes back in the block down below


im having problems too but i read somewhere and it might be my hondata..
