Hi Guys,

Good Day! I would like to ask on the primary cause on why my spark plug at cylinder 2 is wet with waht i think is "water".

I don't experience any overheating problems but I have to add a cup of water at the coolant reservoir every week.

My car also jerks at low rpm at 1st and 2nd gears.

Hi there,

If this is water, the plug will normally turn a dirty brown colour, you can also get a head check done, this will detect any exhaust gasses in the cooling system, a sure sign of a head gasket problem, start here.
