What's wrong with these plugs?
There is black soot (carbon?) build up around the tip. Attachment: image_00036.jpg [ 70.85 KiB | Viewed 116 times ] Attachment: image_00037.jpg [ 62.62 KiB | Viewed 94 times ] Attachment: image_00038.jpg [ 32.42 KiB | Viewed 126 times ] Attachment: image_00039.jpg [ 43.65 KiB | Viewed 96 times ]

Um dude, retake the photo's in macro function on a decent camera and we'll tell ya.
Can see much past the blur, they look a little to hot to me, although hot and black dont go together. Is the black on the centre electrode, ground electrode, thread?

The car is stalling when you switch from Petrol to LPG while the engine is still running.
I thought it might be the spark plugs.

Hold the rev's up when changing, its a pretty hard task to change from liquid to vapor with 500rpm to spare.
Or change when in motion.

Yes, I do that and it works.
However it didn't do this before. It only happened once I took it to Automasters so I was suspecting it was the plugs.

Yes, Automasters changed the plugs to Bosch Super Plus.
So I went to Titan Ford today and bought genuine Motorcraft/Denso Spark Plugs. It is still stalling when I switch from petrol to LPG.. BUT when I start the car on Petrol there is a much stronger and solid (better) starting sound with the genuine plugs.
