I threw a cel and my engine idles at 1500 even after the engine is warm. It has a constant fluctuation from 1200 to 1500 when I am in neutral. I am about to get the code read, but any ideas? It seems that I always throw a cel when it is cold, and it goes off after a few times I drive my car. It is cold outside when this happens too.
After I posted I went to go get the code read and I didn't throw a code...? The idling is fine now too...? Anyone ever had this problem?
