Idle Drops Car Stalls
Hi, I have a problem with my car. Basically when I come to a stop the idle goes down and eventualy stalls the car.
It's also stalls it right away when I turn up the AC.
Can anybody tell me what is going on?
I have a Greddy Type S BOV Recirculated, checked the receric lines and tighten all the clamps.
The BOV is connected to the BR Upper Intercooler pipe, I also tighten up all the silicone hoses connected to the IC pipes.
I already changed my plugs to NGK BPR7ES gapped at .23 Boosting 28psi with Metahnol Injeciton.
My intake is the HKS RS that has been tuned in conjunction with my Stage 4 mods and Alcohol Injection.
This idle problem only started happening when I installed my Defi BF Boost Gauge with Boost sensor and Defi Control unit.
I already checked all the boost lines and it seems there are no leaks to be found.
Can somebody help a fellow evo owner.
Thanks

I don't think its the BOV, plus I already checked all the connection to the BOV for leaks.

Is there like a fuse that has been blown to control the idle? When I was installing the control unit I somehow shorted the 10amp fuse for the accessory lights.

When I was in a hurry to put back in my blitz BLM, i forgot to ground it correctly (i just put it together using electro tape. I had this issue and i thought it was my intake or something causing it. Forward 3 days after and I decided to ground the gauge correctly this time and my idle issue went away. My gauge was lighting up but it was flickering all the time. Now that its grounded correctly its on constantly. Also I read about how when you tap into a power wire (if thats what you are doing) and there are 2 leechers off that single wire, you might want to have them about an inch apart. Thats what I've read but I don't have enough goodies inside my car to see if it's true.

Just try another bov, just to see if it works. My friend had idle issues and would not believe that the stock bov was leaking and giving him problems all that time. So he ended up paying for a Forge bov to fix the leaking stocker during his tuning. Maybe your type-s has a leak... Just another point to check.
If that doesn't work.. check the connections where u tapped the boost sensor. T-fitting not be snug or what not.

I really don't know how they figured it out other than replacing it.. at least for the stocker. Not sure how the greddy is setup, but if u know someone with a stock or aftermarket bov...swap it out and try.
At least you can rule it out for sure, if that is not the problem.
With my friend's problem.. everything else was set up ok. Made boost ok and IC hoses were fine... just the idling problem was the only thing wrong. When they dyno tuned his car, they finally figured out it was the bov. Replaced it... no more problems.
