Adjusting fuel at idle and while crusing?
Phillip
Hook up your care to a scan tool and check the operation of your O2's. Verify they are responding/acting normally. Notice your l-trims - see if you have a large split - or just large values. Make sure you don't have any exhaust leaks.

** cold idle is not controlled through the O2s, so if happens only when it is cold, you can tune this.
** if you have a big cam, a little more spark advance down low may help the car run smoother.
