I recently installed a oil catch can, IDK if that is involved or not so I thought I would include it. I was driving the other day and my car shut off (stalled) when I was on the highway going about 60 in 5th I put the clutch in b/c there was a traffic light and applied medium pressure to the breaks and the car just died, I tried the idle relearn and ECU reset neither worked, thankfully the car started right back up. Any suggestions on what it could be?

 

Possibly a vacuum leak.

 

So you think it would be the catch can causing a vacuum leak or something it was a pretty cheap CC

 

I'm thinking that you were unplugging big vacuum lines and need to check to make sure everything is on tight. I doubt it has anything to do with an inexpensive CC but you should make sure you didn't miss anything that needed to be plugged.

Slamming the brakes takes a lot of vacuum power and if you have a big enough leak the rpm drop can stall the motor.

Just to verify it's not some kind of vented catch can right

 

it is a sealed CC, I will check all of the vacuum lines and make sure that they are tight

 

You should also check the lines once the engine is good and hot after a freeway drive to make sure they aren't getting soft and squishy which causes them to collapse. Doesn't cause stalling but still something to verify, if you used high pressure fuel injection hose then you're fine.

 

^ on this note maybe check your power brake hoses for vacuum leaks. The one on the plenum has a one-way valve in it, and the one at the booster has a small plastic restriction in it.
