Our car runs sluggishly when it first starts. When pressing on the gas, it barely goes. However, if you let it sit for about 1 minute, it runs normal. The issue seems to be more apparent when it is cold outside.

You're going to need a scan tool to analyze the sensor data and look for something out of place like temps sensors reading wrong or an extremely lean mixture that would indicate a vacuum leak.
