Question about Mitsubishi Colt
Just bought a 2004 Colt 1.5L CVT. Today was the first time I drove it from cold and when I put my foot down to take off from stationary the engine died. Kind of felt like it ran out of gas as I tried to accelerate away. Or what it feels like in an old car when you pull the choke out when the engine is already warmed up. It started up again fine and did the same thing again. If I only put the foot down lightly it didn't die but it was like the engine was choked or something. As the engine warmed up the problem went away slowly and once it was up to temperature the problem has gone away completely.
All cars are sensitive to cold .it being a new car you can turn on the ignition for say 30sec to a min before cranking to allow the oxygen sensor heater to warm so it can read properly and will help in these conditions .also a new set of spark plugs can help too.

SOURCE: Cold Start Idle Issue
Problem might be the air control valve, it's located at the right side rear of intake manifold and has a hose going to the air intake duct from the air cleaner, as a test you might try pinching off that hose when the idle is a problem.

These cars are notorious for intake manifold leaks. This could also be a throttle position sensor. If you have a MIL (check engine light) I would scan it with an OBD II scanner and pull the relevent code off the scanner it will give us a much more accurate direction to proceed
