As stated in tiltle my engine after warming up idles low. When I come to a stop it idles about 1000 and then drops down to about 5-600rpm which causes it to sputter and feel like it is going to die. This started a few weeks ago and the check engine light has never come on. I've tried adjusting the idle, but it still does the same thing. Last night I thought I had it adjusted right and then when I went to drive it the tach would stop and hover around 1500rpm for about 2 seconds and then drop down to a thousand Has anyone else had this problem? Any suggestions? Please help, I don't want to have to park my rex.
