this is the third time i have posted something for this problem, im hoping this can be the last. so here is the problem. the car starts fine and warms up fine and idles fine when im not moving. whenever i am moving the temp guage falls almost all the way ...this causes the idle to be high when i then come to a stop, i think because the IAC valve thinks the car is cold. Also i am getting horrible gas mileage and i think it is all related. Please give me some ideas to work with.
If you need more info just let me know ill check this post regularly...thanks alot!
