Question Low RPM's at Idle with HKS SSQV BOV

Ever since i installed my HKS SSQV blow off valve i have noticed the car idles at like 600 rpms then ever so slightly shakes and the rpms raise to around 1000.. it keeps switching back and forth like that.... Is this normal with the BOV ??? Let me know - Thanks!

Sounds like you've got a leak. You should have a nice steady 750~800rpm idle just like stock.

what he's saying is you prolly got a boost leak....meaning your bov is broke or not working properly. did you damage the gasket when installing the bov? try tightening up those bolts again and see what happens. maybe your bov adjustment screw is set to loose.(i heard of people braking theres that way)

schafer, I'm pretty sure there are meets in Sacramento. Go to one. There's bound to be someone there who knows what they're doing and can check for leaks and set the adjustment bolt on your BOV. Do them a favor and bring some soapy water or a spray-on leak test solution to check for leaks on the hoses.

It is most likely a leak in the gasket or the vacumme line. Check those two first.

Its either a leak or you have to adjust the nut on the back on it. Run the vehicle and spray some soapy water on the lines.

When I first ran mine, evertime i shifted to nuetral, my car would stall. I had to adjust the nut on the back side to correct this. This is stated in the instructions.

I have the opposite issue, My car has always idled at like 500 rpm...never had a problem...it shakes a little bit sometimes though...I just rev the engine at lights though so it's not really an issue.
