Tom,
The spark plugs for that vehicle is Champions. Not anything fancy, just a resistor copper core plugs. DO NOT INSTALL DOUBLE OR SINGLE PLATINUM PLUGS. No bosch, no splitfire, nothing but the champion plug.

ANy other plug and you will start have random misfire codes and other "weird little problems".

I have been a shop owner for years and I tell you this because i have fixed weild little problems just by installing the correct plug. ]
You should change the plugs every 30K miles as well. Look in your owners manual and it should tell you your service schedule
Good luck

I usually change the spark plugs on all vehicles every 10,000 miles.
