it is an early 06 model..... and i do have the older version of the coil packs... i need to get the oem version, i should also check the plugs as well. i did clean the MAF today and reset the comp and that seamed to help with the idle issue on the way home but it still is alittle on the ruff side...What's the build date on your car? Earlier builds had older coil revisions... many have reported less misfires, smoother running with the latest "D" revision of the coils.
