bruceb58 Posted April 15, 2007 Share Posted April 15, 2007 What is the spark plug torque specification? Also, besides the top engine cover and the front timing belt cover, which items need to be removed to access the center spark plugs? Looks like a large portion of the fuel injection air intake needs tobe removed. Quote Link to comment Share on other sites More sharing options...

Gaskets are reusable if not damaged Use throttlebody cleaner if possible, some regular carb-cleaners can damage modern EFI sensors/plastics or leave residue that can corrupt Oxygen sensors.. mike Quote Link to comment Share on other sites More sharing options...
