Well that 100K spark plug and coolant change thing only applies to perfect "operating conditions". I bet 90% of us don't live in that imaginary world. LOL!! I agree pull 2-3 plugs out and inspect them. I would also recommend u start adding a bottle of the Chevron Fuel System treatment at every oil change, that should help her stay clean internally....
