Idle Problems after running

[or4nges]

Haven't been able to find something about this in the threads yet. But my mklll is having a problem idling after a load or a 35minute ride of maybe a constant speed of 70mph. Stock turbo 10psi, hks boost controller, aftermarket intake, greddy type S BOV, 3'' turbo back exhaust. Iunno what it is but when i neutral it likes to almost die on me, but when i stop and try to slowly backup or park it seems like it gasps for air and sometimes dies. Maybe the stock turbo can't run that much psi or the stock intercooler isn't doing it.

Advice guys?

This is the problem u get when your BOV is venting to the atmosphere. That "almost dying" part is the engine hesitating because it expects the air that was released via the BOV to be recirculated back into the system. I had the same problem with the greddy type s as well. I could never get the engine hesitation to go away with it. Strangely enough, im now running a Greddy Type RS and problem went away. You can also try tightening up the adjustment screw a bit.

What are you doing with the throttle when this happens? This wouldn't have anything to do with the turbo or IC at low throttle, or even high throttle for that matter unless you had a really bad boost leak IMO. Also, the stock turbo should be able to do 10 lbs just fine unless it was on its way out.
