Engine Mechanical problem
2000 Ford Taurus 6 cyl Front Wheel Drive Automatic 165000 miles

I have a 2000 Taurus- the engine started idling at 2000 RPMS. After a few times doing this, it started climbing to 3000 RPMS and higher.
I replaced the IAC and the EGR- the engine will " run" at 500 rpms when the IAC is unplugged- however it stalls until it is throughly warmed up, unless I goose the throttle.
the local ford dealer could not tell me anything- they wanted to replace the computer, but said this may not be the issue.

Have you checked for codes? How does it drive? Did dealer diagnose car or was it a phone call? ECM controls IAC so if unpluging brings idle down that tells the ECM is doing that. If no codes for crank sensor then ECM is a possibility.

Car drives ok- small decrease in mpg. Rpms normal within the gear ranges.
The dealer had it in the shop, they could not get a clear diagnosis. They wanted to replace the ECM just so they could be sure that was not causing it.

Once I plug the IAc in- the check engine light goes off. No codes except for the IAC being unplugged.
