- Turbo audibly spools - Boost gauge reads full 7psi - NO BOOST The car feels like it’s a KA motor. Also, it’s been constantly stalling, most commonly under braking. Or when I heel-toe: the revs go up (obviously from pressing the throttle) and then they suddenly drop and it sometimes stalls. It seems like it’s been running a bit rich too, and some times too lean. This started yesterday morning. Can’t be a vac/boost leak as the gauge is still reading 7psi (taken from inside the intake manifold). Can’t be a shot gasket or anything because the turbo is spooling. Please help. ---

Could it be the AIV or PCV just a guess … might be it… others agree or disagree… ? just a guess…! Corey ---

can’t be a shot gasket because the turbo is still spooling? NO BOOST? yet you have 7 psi at the intake manifold? I hope your post is a joke because its full of contradictions. ---

Just because you are making boost, doesnt mean you dont have a vaccum leak. When under no throttle at idle what is your vacuum reading? When under deceleration what is your vacuum? Just because you are making boost doesnt mean their isnt a boost leak. Check your turbo manifold gasket for leaks, I had the exact same problem before, the gasket was fucked. As for the stalling, try tightening up the bov a bit, or adjust your tps. I can almost guarantee you that the stalling after the rpms fall, is caused by a “too-loose” bov. ---

Sounds like it IS a boost leak. So when you press the brakes, the vaccum booster causes problems. You can build alot more than 7psi and still have boost leaks. ---

Maybe you’re not heel-toe’ing enough… you should mention that more, cause it makes you sound like a pro !! Watch F&F again, make sure you’re heel-toe’ing properly, then double check you’re hoses… Sorry I’m in a bad mood today… ---

Watch F&F again, make sure you’re heel-toe’ing properly, then double check you’re hoses… > > Sorry I’m in a bad mood today… umm…it’s quite alright. ALSO: I don’t even have to press the brakes for the car to stall, sometimes just decellerating in neutral will kill it. I cleaned the mafs and the throttle body, but it didn’t do anything. anyways, no it’s not a joke, those are the exact symptoms. I know the problem makes very little sense. I’m running a SAAB recirc valve, no BOV. But I guess it could be that. No to changing flywheel or clutch. If it was indeed a boost/vac leak, wouldn’t the idle be f00ked too? She idles perfect. I figured if I’m making boost but the car isn’t boosting, it could be fuel? or spark? On a good note, I took it to a mechanic who’s gonna spend the day checking everything out. I’ll get back to everyone with whatever he finds. Thanks guys. ---
