There really should be a (sticky?) thread about problems important enough to cause noticable drivability issues, but don't trigger the Service Engine Soon light. So here it is...

Also keep in mind "burned out bulb" shouldn't be a good excuse - at least with last generation Grand Ams that do a quick POST (power on self test) with all the dashboard indicators. (Some people think that's for show when the car gets turned on, but it's a nice feature actually.) Any lights that don't come on then or guages that don't move probably aren't working.
