Does the larger gap mean the plugs were gettin bad??? Got em done today anyway, one more step in the tuneup completed. Next... Fuel filter and O2 sensor.

The larger gap means they were past due to change.

Might I suggest a change in O2 sensors, and a fuel filter change?

I'm planning on doing both very soon. It started to give me a lil sputter tonight. I plan on getting the O2 Sensor from GMPD.com #25312184. I can get a good deal through NAPA, but they only sell Bosch. I can check on one more place in town though, some UESCO Warehouse is an AC Delco dealer.

Also, there'* not a huge difference in fuel filters is there?

I'm gonna be able to get it for $42.75 I think is what I was told. About the same as rockauto.com or gmpd, just without the shipping.
