Fast idle problem.

OK, it turns out my engine will not go to fast idle when cold. It works for about 30 seconds and then drops to normal idle, which means it dies. I have to keep giving it a little gas until it warms up.
Since it is a fuel injected motor I do not see a place to adjust that.
Any ideas on how to get it running right?
Thanks!

If you're lucky all you need to do is clean the idle air control valve. I'd start with that.

Where can I find that? My shop manual I bought on Ebay will not be here for another week or two. Many thanks!

Two screws hold it to the top of the intake manifold, it's round, about 5 inches long 2 screws attach it to the manifold & theres a 2 wire electrical conector at one end of it. 2 more screws to take it apart & clean it. This is a 2.9 i presume?

If that doesn't work it might be the ECT (coolant temp sensor) reading that your warmed up. I would pull the codes before replacing anything.

OK, people keep talking about 'pulling codes'. I have never done that (never had a car with a computer in a car before).

I found this scanner on Ebay:

Is it any good? Thanks!
