I put one in last week in my 84 TQC... I picked it up form a Saab dealer
for $40.00.  7/8 fitting and its made by Bosch.  I think the Saab guys
call it a 'hooter valve'.  I don't know how well it works because I'm
having a problem with the car not pulling strong after about 4200 RPMs.
It's almost like it has a slight misfire or fuel supply problem.  I have 1.4
bar boost and have checked all of the pressure side for a good seal.
I'm open to some thoughts on what else I should check.  Also note that 
this is an Euro spec car so I have some odd type 'emission control' devices.
