yea, i guess its normal but today it actually stalled out completely twice. kinda sux

 

could it be my spark plugs? too little back pressure?

 

I just went and got an autometer boost/vac gauge (had boost only gauge till now) for free from a friend and installed it. Also, i took the MR valve off and swapped it with my stock plastic valve. No more stalling but.....
My vac reads at 16-17 at idle. Im pretty sure im supposed to be at 20 at idle....right? am i leaking?
where should i check for leaks if i am?
damn....1 problem fixed and now a new one.
