pretty bad.  She stalled, coughed, and hesitated.


the warm up reg., aux. air and lambda pulse.  OK.  Tested all the
vacuum lines, found a bad diaphragm on the charcoal canister.
Suddenly the stalling and coughing stops.  The hesitation is still
around.  When its below 60deg the car starts fine.  I wait about 30
seconds and slip into gear(auto).  If I give any gas I have to wait
maybe 10-20 seconds before the car moves/idles up.


Disconnected the fuel lines. No pressure!  Ok, that's not good(tested
Sunday, last driven Fri.).   Tested the cold/hot control pressure,
tested just fine at the high end of the range(over the 40psi system I
saw).  I could not test the system pressure by jumping the relay.  I
jumped 30 & 87 and the fans turned on, not the fuel pump.  I jump 30 &
87b and the AC pulley jumps on.  Using the ignition key I tested the
system pressure and only got 40 psi(I swear I closed the CIS tester
valve??).  Weird but everything else worked fine.  As it turns out,
the residual fuel pressure stayed at 40 psi for over 30 minutes. 


up the vacuum gauge to the dist. port on the throttle body.  At 850
RPM idle no vacuum?  At 2000 RPM, 19 in-hg.  No where in Bentley do
they suggest vacuum readings as a test.  Is this a healthy reading?
I'm assuming that this port has no manifold vacuum with the throttle
closed! 


spark plugs.  And the throttle body was cleaned twice, by SAAB then an
indie.  What gives?
