Those with HKS SSQV

[SkyHawk Ecks]

For those who have ran the SSQV vented to the atmosphere, what did your vaccuum read?

Like many others, my car idles like shit (normal range 600-700 and stalls easily) and the vac gauge fluctuates from 10-12 at idle. Otherwise the car runs fine, boosts well and everything. Did it significantly improve (eg: go back to normal vac range of 18-22 at idle)?

I dont even have a supra but if you read on here you'll find reseting the computer is a good start.

Mine reads about neg 20 at idle/cruising...

What would resetting the computer do, exactly?

Yur car prbably idles like shit because you have a vacuum leak somewhere... Look for a hole, loose vacuum connection, or popped vacuum line...

I'll double check again but as far as I know, I have no vaccuum leak other than the SSQV being vented to atmosphere.

mine did that but i just got the hks vpc and now it runs fine, note i have the HKS ssqv, my friend told me my why it does that but i forgot, but i have heard it happens to alot of cars. i forgot what to do to get rid or it, i think tuning or something (sorry i will tell you when i do remember). i hope this helps

thats not a vacuum leak. the BOV will have no effect on your idle.

a few things can cause your car to idle like shit and have a low vacuum reading. vacuum leak (most likely), a blown head gasket, bad AFM (check codes) and the list goes on.

i have a SSQ and have never stalled or run like crap.

i have the hks too. not a problem except for running it up to high rpms and pushing in the clutch make the car shut off.

Supposedly the SSQV is impossible to leak, unless your fitting is bad, its part of the design. I'm running it and idle fine, 20 vac. My EGR system used to be bad and that was making me idle really bad might check that.

i have the same problem

with only -10 for vacuum, you definately have a vacuum leak. it's not the BOV. my vacuum is at -21.

I have a Monza blow off valve that looks exactly like the hks,only i have mine venting back into the turbo elbo,as far as the idling prob,ISC valve?

i have the same problem

That might be your dash pot acting up or your bov isnt getting a good vacuum to pull it open... Maybe loosen the screw in the back of the bov... If that doesnt work, adjust your dashpot...

I've checked all the hoses for vac leaks, used throttle cleaner to see if it got sucked in anywhere and I still haven't found anything. I took it to the shop and they gave it a quick look (and also did the throttle cleaner spray). He said one of the possibilities, was that the valves may be too tight or something to that effect.

This is all weird as last tuesday the car was running absolutely perfect, idle at -21, boost was strong and all. Then it all turned bad when I raced from a light, that little grey connector to the starter got unplugged and the idling turned to shit!

i have the new style bov which doesnt have the screw on the back

Me too, all the same symptoms... and I don't like the sound

Think I've got it figured out. I busted the IC hose going from the turbo to the intercooler. Boo for unmetered air.
