Spark Plug Condition
« on: April 16, 2013, 06:58:09 AM »
Hi! Here is a photo that I took this morning when checking my spark plugs.

Cylinder 2 plug is really different from others:

3 month ago when I first time noticed this - cyl 2 spark plug was changed to new one.
Then I swapped cyl 1 & 2 coils to see if its a cause. As we can see - no difference.
Plug wires are fresh - was installed 10 000 km ago.
Compression - 14 approx.
When testing for spark - when plug is outside of engine - its present.
When disconnecting plug wires - engine is responding on every cylinder same way.
No fault codes.

So, why plug N2 is not looking normal?
