Ok the info first, just over 150k on the odometer and these are placed #6 to #1 from left to right as they came out of the engine.
My concern is the discoloration of #1, could this be caused by a leaking injector? Then, #6 and #5 seem to be running considerably leaner than the others, is this normal for a Non-CA emissions engine. (only have 2 O2 sensors 1 just in front of the cat and the other just after) Any insight would be appreciated. @Chris , @Jerry Bransford , ??
