when I crank my car in the morning when the motor is cold it runs bad when I gas it but when the engine warms up it runs fine. What is causing the problem and what can I do to fix it.

It sounds like a bad temp switch. That is the part that tells the computer ambient temp and coolant temp. Based on that, the computer determines how rich or lean to make the air fuel mixture. Is there any smell of fuel or anything that you can think of that may help? Also, let me know if the check engine light has come on.
