The problem has changed. I'm certain now that the plugs are installed correctly. This may or may not be coinsidence, but first of all-- Auto Zone's diognostic showed no codes at all, but the fan stays on all the time, the idle is rough, there's a squeeling noise on excelleration after driving a distance and the 'service engine soon' light remains on. Again, it's a 2003 Saturn Vue 4 cylinder, 5 speed with 80,000 mi. Thanks!
