Question about 2006 Toyota Corolla
I have seen this problem countless times, and no computer can give you the answer, The problem is your ECT. The Engine Coolant Temp sensor. It tells the computer what temp the engine is at and it uses this input to regulate the fuel. When the engine is cold, the fuel is increased to act as the choke for easier starting. As the engine warms up, the fuel is cut back. When the sensor locks cold, the computer runs the engine in choke mode all the time, sending the fuel ecom\nomy down the toilet.
