  Is your check engine light on? This rough idle can be related to emissions control system problem with sensors, etc. These driveability problems can be complex, and if it does this every time without fail, I'd take it to a shop and have a technician go on a test drive with you so you can show him what you mean.

  Have the Oxygen sensor checked....My 2005 Impala started idling rough at 97,000 miles...I checked the computer codes with a code reader....reported my oxygen sensor in front of the cat converter was bad....I replaced it and problem is gone.
