3.0 liter ohv ford taurus ses 2004,
when the weather changes from summer to winter my car does not seem to run right.
When weather is cold I will start the car and right away it goes to a very high idle, then comes down to normal idle. Once the the car starts to reach operating temprature it starts to spit and sputter, as if is ready to stall. Sometimes I will get a 170 or 174 code reading lean in either bank.
Please advise me of the problem.
