won't hold idle on startup
I have a '94 GSR and just recently the car has been running poorly. When I go to start the car after its been sitting for a while (overnight or something), it doesn't want to hold idle and will even dip as low as 200 rpm before puttering around and wanting to die. I usually will hold the revs at 1500-2000 rpm for like 30 seconds to let the car kind of warm up. This seems to help a little bit but only until after the car has been run for a few minutes. I don't seem to have this problem as much later in the day, when its not as cold and when I have already driven the car that day. Could this be the Idle Air Control Valve or something else? Would resetting the ECU help at all? (I am running a Skunk2 ECU and recently swapped stock cams back in for my Type R's). Thanks.

the motor is just cold. it could be a bunch of things, basically anything that might be outside of operating temperature (ths dizzy, the spark plugs, etc.)
my un-educated guess might be something to do witht he engine getting spark
