Re: [DML] 3 Brass Screws Infront Of Engine

The reason they should be closed is because in the trim that our PRV is in,  
the idle speed motor electrically controls idle speed, where as other  
applications of the PRV do not have this device and would then use the 3 brass  
screws. The one screw is what sets how much air goes past the throttle plate at  
idle while the other two are for balancing each side of the engine if need  be.  
That's why the screws should be closed. If they aren't, the idle speed  motor 
cannot do its job of properly metering air at idle speed.  If your  car runs 
WORSE with the screws closed down, well that's because someone thought  they 
should be used and they messed a bunch of other stuff up while compensating  
for letting air through which THEN would mean that car was never set up and  
running right in the first place.

My guess  would be to tighten them all down.  I'm sure someone who is   
more experienced in the field can elaborate on why.

In any case,  tightening them down had no effect or change on my car.
