Have a Nice Day? Stalling at Idle after Minor Mods

Just put a TurboXS Ti Turboback, TurboXS short RAM intake, and bov-rfl on my 2006 wrx. I am having problems with an inconsistent idle. sometimes it will be fine around 600-800rpm and other times will spike up to 1500 then back down to almost stalling repeatedly until it evens out at the 600-800 mark or simply boggs out and stalls. How do i fix this? Is it strictly ECU and o2 sensors misguaging the A/F ratio? If so hoe do I approach this prblem?

no, the problem is coming from your rfl bov. Those things leak so much air at idle and really screws everything up. Put the stocker back on and im sure you will notice a difference.

Did you disconnect your negative battery terminal and drain the rest of the power before doing your mods?

+1234 take it off and check, if you want to try and keep it on you may need to add some washers in it

I agree you are leaking air somewhere. For a more general approach, use brake cleaner and spray around the RFL and the intake manifold to find the leak. When the cleaner gets sucked into the engine it will cause a momentary surge.

Actually, you might want to take a clear plastic bag or plastic wrap and put over the BOV orifice. With the engine on, midly blip the throttle to see if that valve is leaking. This is how I tuned mine along with actually driving etc. I bet yours is hanging open momentarily after it rests back down to idle.

it is your bov! and i am 100% positive on that! take it off and take it apart. clean it and lubricate the piston with something lite! if it still does it then sell it to sum dum dum on nasioc.

His TXS valve most likely uses washers to adjust the tension.

I'm using the RFL with zero issues. Works as advertised. Just took some adjustments to get it right.

It's probably the stupid blow-off valve or the intake. Both generally considered not the best of mods.

I hate to flame,, why do people insist on the CAI and the BOV? I think you are better off filling your tires with nitrogen...

thats correct. I was having probs with my car aftere my install and i tried switching the maf sensor around and the car ran for about a second. Most intakes are idiot proof anyways.
