[QUOTE="rapcom, post: 22007, member: 191"] For a variety of perfectly good reasons, this evening I removed my four spark plugs (twin plug heads) to check the sparks. With all four plugs mounted in my special jig (a piece of aluminium angle with four plug-threaded holes in, with an earth lead with croc clip), I was puzzled to note that I had three blue sparks and one with a decidedly pinkish hue. The two twin-output coils are identical, the leads are all the same brand and almost the same length, appear to be undamaged, and all the plug caps and spark plugs are identical. The pink spark always comes from one particular coil output. Can anyone give me a clue as to why I have one pink spark? [/QUOTE]
