I just swapped the engine in my 2000 tour. It is the 2.5. When I start it, it will rev to like 2300 rpm for a few seconds and then come back down where it should be. Any ideas. I really don't want to get a really high rev on a cold start. I was thinking the idle air control, but not sure. I have no check engine light and no rough run. Any idea???
Thanks in advance!!
