First step, have the check engine light scanned - for free - at any local auto parts store such as; Advance Auto, Auto Zone, NAPA - for the stored fault code. Having the specific fault code will assist to pinpoint the problem or issue you are having.

Ignition coils will operate at a raised (underhood) temperature. The best spark plugs would be OEM (original) equivalent or better - those listed below are correct for your vehicle and application. The NGK spark plug is what your engine was origninally equipped with from the factory.

AUTOLITE Part # 3923
DENSO Part # 3145
ACDELCO Part # 41602
CHAMPION Part # 344
NGK Part # 6458
