Okay, I have a bad idle problem, I tried changing the mass air flow sensor, helped a little, then did a complete tune up, not much change. It seems the colder it is the better it runs, so I thought maybe a air temperature sensor? I just do not know, one thing though, it seems in the summer it runs a lot worse than in the winter, makes me think something to go with the temperature control something. Please help! Thanks

It sounds like you have an engine coolant temperature sensor issue. I would try changing the sensor.

Here is a guide and the location (below) to get the job done:

Here is the location.

Please let us know what you find. We are interested to see what it is.
