2000 Ford Explorer Idle Issues
Whenever I start my 2000 Ford Explorer the RPMs start at 1000 and drop
down to 500. Sometimes its starts for a second then dies all together. Then there are other times where it starts fine and holds RPMs, but when I am halfway to my destination, the RPMs will drop back down to 500 and feel like its about to die. I've tried cleaning and lubricating the battery and the weather here is not that bad, so I dont think that that would be an issue. Any help would be greatly appreciated. Thanks. |

Sounds like your IAC needs cleaning or replacing - lots of stuff written on
it. Google "Explorer IAC". Could also be intake gaskets, but try IAC first. -- Allan Williams > wrote in message oups.com... > Whenever I start my 2000 Ford Explorer the RPMs start at 1000 and drop > down to 500.

Is that while you're trying to drive down the road, or sitting at a stop? 500 rpm at a stop is normal. If it happens driving down the road... does the 2000 have a fuel pump relay? My 1994 had a problem like that, caused by a bad fuel pump relay. -Paul |

Normally it would idle at 1000. Not sure if it has a fuel pump relay, I'll look into that. Thanks. |

It adjusts the amount of air the engine gets at idle. I believe it should idle at 500 rpm when warmed up. If it doesn't, it's most likely the IAC which is known to stick or get clogged. You can replace it or there is a procedure for cleaning it, do a Google search for that. The other common problem is intake manifold vacuum leaks. That affects idle and can vary because the parts expand/contract with engine temperature. -Paul |
