high idle

[gltasn]

i just did the new o rings in my tb(originals nowhere to be found) and now have a high idle(1500rpms), and ive chased down every air leak. new iac. i want to try thr biss screw but found conflicting threads. one says it needs to be grouned thru a brown jumper term. others say just screw it.

not hard to do just want to do it right the first time. so is grounding really nesc(sec gen 95 3k vr4)? why does it matter? huge thanks for speedy replys! j sin

did you bypass the coolant lines from the throttle body?

[gltasn]

nope still there. if its a little shy of coolant could it cause my high idle(tb highest area for coolant to reach)? j sin

[i3igpete]

yes, see the section on stealth316 regarding the FIAV.

it ran good before i did upgrade. when will i learn to enjoy it when its running good and not try perfecting it so much! j sin

any answers?

I just changed my plugs, injectors, and now it's idling at 1500.

the BISS screw on the tb has no effect. The BISS can be turned ALL the way in and the car still runs at 1500...haha.

Any update on this?

I did almost the same thing. I'm idling at 1200rpm.

mine is still high(1400) then it goes to 1100 after it warms. ive heard of others running this way for extra oil pressure when running td05's, so i havent messed with it. i did try messing with the idle screw but it would die.my fiav might not be getting the coolant it needs to idle right. ive pulled my rad. a few times this summer triing to keep it from purging coolant. it still does under heavy load(over 3500rpm's). i can drive it hundreds of miles without spilling a drop but if i do some 1st and sec. gear pulls i will loose coolant.(time to start another thread). j sin
