Hi, I'm new to the forum and hope that I'm asking this in the right area. I have a 2000 DTS that I bought about a month ago. Recently it has started stalling when it reaches operating temperature. As soon as the temp guage reaches operating temp the car dies. I can't even drive it. This happens in my driveway as I warm the car up. The prior owner said he changed both crank position sensors. I cleaned the IAC and there are no vacuum leaks. Any help would be greatly appreciated.

Sorry no check engine light or codes

 

Thanks for all of your help everyone. I removed the IAC again and cleaned the orifice very well and the problem was solved.
