Talking Bonehead Maneuver!!

Embarassed to admit that after reading another post and looking in the Bentley manual it suddenly occurred to me that I may have flipped the leads for the O2 sensors and plugged them in backwards. Sure enough, switched them and the car idles perfectly. Will still change out the old plugs with identical replacements and forget the +4's for now based on what other posters are telling me.
