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?

Yes see if you can get the Ac Delco Part there...

On these O2'* .... Some people say if the PCM is not throwing the SES light( MIL ) Then there is nothing wrong with the sensor... That is totally and absolutely not true...

On these cars the O2 has to be about to take its final breath, before the PCM will let you know... In other words the sensor will be dead.... The signaling rate can drop to next to nothing and the PCM will not let you know, unless you have a scantool to monitor the sensor... At 130K its well past due for replacement..

Let us know what the wharehouse charges for the AC Delco O2

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.
