P0301 Update S70

posted by  someone claiming to be Eddie G on  Fri Sep 2 05:43 CST 2011 [RELATED]

Last night I took out the Bosch Platinum 4 prong plugs and installed the Bosch Copper and gapped accordingly. The rough idle has disappeared, but I still get a CEL at about 70 MPH. Before the new plugs, the CEL would trigger at about 25 MPH. My next step today is to put in a new rotor and cap. Any other suggestions?
