Like Jan, I don't know the 4 cyl engine that well. Everytime I fill
up, I thiink your friend has the right idea - he / she gets the
Mustang experience with a little less bite at the pump. :-)
Anyway, on the 8 cylinder, I'd look at the idle air control, if
present on that motor, and possibly the TPS. I heard both suspected
in low idle driveability concerns, although Jan's vacuum ideas are at
least as good. The IAC gets gummed up over time, and is an expensive
piece to replace, but 20 mins with a can of carb / throttle cleaner
has NEVER failed me.
