won't idle until warms up

[upstart555]

Hello All,

My 91 325i won't idle without pedal assistance for the first 5 minutes in the morning. You would think I would just need to replace the temp sensor which I did but to no avail. I also checked for vacuums leaks and found none. Anyone else had this problem and fixed it? I am at wits end.

Idle control valve?

Has the adjusting screw cap on the MAF been removed?
Has the idle control valve (like what Scott said) been tampered with?
Have you checked all electrical connections under the bonet?
More info.
