I have a 1997 Honda Accord SE. In cold weather when I start the car, the Idle fluxuates until the car is heated. I have to run the car until the temperature comes up, then it's OK. What could this be? Thanks,, Bob

. Clean the Idle Air Control Valve (IACV), throttle plate, and throttle body:

. Replace the Engine Coolant Temperature (ECT) Sensor, which affects fuel injector pulse width. The ECT Sensor is a temperature dependent resistor (thermistor), whose resistance decreases as the engine coolant temperature increases. It provides a richer mixture when cold, leaner mixture when hot. They become corroded, due to not changing the coolant frequently enough, flood the engine, and waste a tremendous amount of fuel. Look for a sensor with two wires going to it, located under the distributor.

Thanks for your help in this matter. I'll replace this part before it gets cold
