Here is a strange one. I have a 1998 Dakota. During the summer it runs like a champ abd I have no complaints. (well, maybe one but that is for a different thread) When it gets cold outside (I live in upstate New York) It runs fine except when I put it in park or neutral. The rpm's drop and the darn thing stalls. This can happen even when the engine is at operating temperature. I dont get it. Does it need a sensor replaced? Any help would be appreciated.
