NGK BCPR6ES11's gapped to .039, or to .035 for longer useful gap running.

Remove the DI with 4 torx screws. Don't overtighen when replacing. I strongly recomment a bit of loctite blue.

A bit of silicone grease on the rubber tips of the DI is a good idea.

Pull the DI up and set aside on its cable.

Plugs are basic after that. Suggest that you blow sand and crud out from the spark plug wells before removal. I like a bit of moly grease on the plug threads, but many don't do this and do not report problems. The issue is the aluminum threads.

Cleaned your injectors lately? Suggest Tecchron Concentrate. This often helps with starting, which becomes an issue in cooler temperatures this time of year after a season of summer grade RFG-II fuels. These fuels are still being pumped.

Check battery cable connectors. Check electrolyte levels. When the tops of the battery plates get dry the batteries can explode.

Air cleaner? What fuel are you running?

If the above things don't help, you might need a new DI. $270 shipped, no tax from http://www.eeuroparts.com. The DI's fail eventually, so you will need one sooner or later. Nice to have one in the trunk and not pay for a tow plus dealer costs. Please post your miles?

Whats in the DI? All kinds of electronics that get heat and vibration. 4 coils, 400V primary voltage, multi spark support, knock condition sensing by measureing the ionisation resistance across the spark gaps...
