Look for vacuum leaks or maybe even a bad injector. The O2 sensor may be
compensating after it warms up. I just had this experience. Turned out
to be pin holes in the intake manifold.

Subject: Does my van want to do a start-up sequence?

In my recent posts, I've mentioned some serious idling problems. They
are really more than that, as until the van is hot, it has no power. I
haven't gone through the Bentley troubleshooting procedures yes, but I
am wondering something as I get ready to troubleshoot.

Something doesn't make sense to me: I can understand why if there were a
problem with, say, a temperature sensor or the idle control valve, that
I might have idling problems when cold. In fact, it runs ok after it has
gotten hot. But- and here's what doesn't make sense, if I shut off the
engine, and start it up again, I have the same problem, with a hot
engine, until it runs another five minutes or so.

This makes me wonder if there is some sequence the computer wants to go
through that's not working out. It doesn't make any difference if the
engine is hot or cold, it doesn't idle right for several minutes after
startup.

Thanks for any advice,
