Cold Weather --> LOW idle @ Startup

Hey everybody
I just bought my first volvo (740 GL Wagon, 1990, AT) a couple months
ago - now that the cold weather has come I've noticed that it idles
VERY low @ startup - especially when cold. I mean, arount 500-600
RPM, on the verge of stalling, unless I rev it up to 1500 for a few
seconds...despite what I've always been taught about treating a cold
engine, in order to even it out @ around 900-1000. I've been told
Volvo's require a few more cranks than other cars to get 'em going but
it seems to be taking about 4-5 more cranks than my friends 91 760
GLE.

Car's got new plugs and wires, clean air filter I'm not sure what kind
of gas to use in the car but I've always gone by the L4 -> 87, 6-cyl
-> 89, 8+-cyl -> 93 rule. Perfect compression on all four cylenders.
135,000 New England Miles.

I've also noticed a funky pulsing idle at a complete stop when in
gear...freaky and pushes the car forward if the brakes aren't down
enough but not enough to cause immediate concern.

Car's fuel injected, I'm not sure which system though.

Thanks Guys
Fred.
