My M60 didn't do that but it was moody when cold too. I put royal purple 20w-50 in it, dinan chip, New o2 sensors, and replaced the resonator with an X-pipe and it was much happier in general and especially when cold. I also did a tune up and changed the fuel filter and added a K&N stock replacement filter. It ran like night and day after all these changes. Just make sure the throttle body is clean and your intake snorkel doesn't have a hole in it. Also check your throttle position sensor.
