1998 Deville/111,111 miles. Dealership unable to detect problem. When first started it runs exceedingly rough until it warms up above 160 degrees or RPMS are raised above 1200. Any Ideas? Signed Rough Starter.

Have you had the 100K service performed? Did they hook it up to the Tech II? I am guessing they did and no codes were found. Some ideas could be:
1) air filter
2) fuel filter
3) oxygen sensor
4) idle control valve

Affimative. Feul filter was replaced 2 weeks ago. I am unsure about the idle control valve. Will replace the other two first. Thanks!!

Also, if you know a technician at the dealership.. ask them to hook the car up to the Tech II. It will show them what codes were/are being registered and when they appeared.
Goodluck!
