I have a ‘98 Cirrus with 2.5 engine. I bought the manual for guidance in changing spark plugs. The removal & installation section on page 1-39 and 1-40 only addresses the front 3 plugs. It is obvious by looking at the engine that something (the intake manifold plenum) must be removed in order to get to the back 3 plugs. By going to pages 3-23 & 3-24, the engine repair section, removal of the plenum is discribed. Is all of this necessary if the ultimate goal is just changing the plugs? Can the fuel line and the throttle body stay connected while the plenum is moved to one side? Maybe trial and error with provide the answer.
