These are showing up when they check my diagnostic codes. My car is also having trouble when I first start it in cold weather. When I push the gas, it takes a minute for it to get going fast. This only happens the first time I push on the gas pedal. I'm not really sure what to do and can't really afford to take it to the dealership to have them check it out.

A professional grade scan tool allows key engine sensor data to be analyzed right off the scan tool without having to do intrusive testing at each sensor. It would be interesting to see what the computer in your car "thinks" is ambient air and coolant temperature when the vehicle is started up from cold and as it warms up. I would also look at scan tool information to see what the air flow meter input, O2 sensor readings, and Air fuel ratio long and short term reads. I would also look for vacuum leaks.
