Yesterday I pulled my plugs and found them to be the Bosch (sp) plug once used as replacement plug for the Ac Delcos. Replaced them with the proper ACs and had the fuel rail pressure cleaned and also added a injection cleaner to the gas. Made a big difference. Engine is smoother and now idles at the proper RPM. Just a trivia point I thought I would share.
