Default Please Help......The car sometimes stalls when I shift to neutral on the road

I have a 2003 wrx with Blitz intercooler and air intake installed, but there is a problem after I stalled these, the car sometimes stalls when I shift the gear to neutral while I drive on the road ( rpm drops to zero and the engine stops)...... so is there any one who knows what the problem is and how to fix it.....Thanks for your help

Just a guess, but maybe with the increased air space due to the FMIC, there may not be enough pressure to get air into the engine when you shift into neutral causing the engine to stall.

Like I said before. . I'm no expert and I'm just guessing. You may have better luck posting this in the FFI forum. If I had to guess, it may be that the stock turbo is not providing enough air to the longer intercooler piping. Most people that upgrade to a FMIC also upgrade their turbo's. If you stick with the factory turbo, you're actually better off with the TMIC. Not sure if other's have upgraded to a FMIC with the stock turbo though.

Best bet is to post in the FFI forum. Good luck.

The motor creates a vacuum in the intake manifold, which sucks air in anytime you're not on boost. That's how normally aspirated cars are able to run without a turbo.

You have a vacuum (air) leak between the MAF sensor and the throttle body. Tighten up all your piping connections.
