ironically, something i was thinking about today while picking up a
starter for the 90Q (btw, you have to remove the RF wheel to do this
job!)

if the intake draws a vacuum on the gas tank, a leaky gas cap (indicated
by no "whoosh" when you've emptied the tank) means some unmetered air is
getting into the engine via that route.  Now, maybe this is only at
idle, but I do wonder...
