[s-cars] low boost

[ELLIEOLSEN at aol.com]

Hi Guys,
 
My car has been running poorly the last couple  of weeks, and I finally 
pulled all the hoses off checked them and put  them back on...no difference, saw 
nothing suspicious yet the car is a slouch not  its normal chipped self.
Recent history...Oil change and i told the wrench to take it for a rid as I  
felt it was hesitating, well he thought it was fine..I got it back and it 
still  only felt like 80% power...After a few days I pop the hood to find the hose 
 coming off the turbo to have blown off completely, great I think put it on 
and  we are back in business..not so fast! I re attach the hose and it did not 
get  much better...Is there something I need to reset ????
Current Symptom...acceleration under-load  is where I feel it  hesitating. It 
does not buck and there is no apparent really loud rush of  escaping air 
(maybe a little it is so damn hard to tell) ...its as if it  wants to fly but 
forgot its wings ... the mad rush of acceleration above 3000  rpm is but a 
fizzle...
 
I took of and checked the M-Man hose, MAF-turbo hose, I checked  the IC-turbo 
hose the touchy feel way but it felt and looked fine.
 
Could this be caused by a bad BPV? 
 
Suggestions of where to look for boost loss with out much sound would  be 
appreciated...
 
PS: It would be cool if we had a color sketch of all the boost related  hoses 
and notes explaining what the car feels like with the different hoses off  or 
torn and what sounds you can expect with certain hose maladies. If this  
exists please direct me to it.
 
TIA,
