my aem was doing that.. it didnt want to restart on a warm start up if it died. i replaced 2 resistors and all was good.
but you should have ~150-180psi i think.. its been a while since i have done a compression test on a s2k w/a thick hg.
but with 90 and 50.. its time for a rebuild, no since in speculating. its got to come apart to fix

just trying to do it the most money conserving way..
the mechanics are baffled since its 80% across all cylinders and dont hear the air coming out =/
I was assuming it was the rings

80% leakage should result in lots of air noise...i assume someone closed the valves before making measurements?
I spoke to another mechanic and he was saying maybe the valve guides are bad and the head is in need of a valve job...and he was saying if there was this much leakage the car should not run..

have them pull the cams out then do the leak down test.
Im thinking I should just rebuild the head already and save some time....

they have to pull the cams to pull the head, may as well take 5 mins and do a quick leakdown
