After reading this, that was some puddle of water you drove though, to get water into the top half of
your motor, enough to wet the plugs. You drive through that much water, lucky you didn't have a worse condition
to deal with here. Water winglets for your Kappa....
Not knowing the current mileage on your odo at the time, IS this the first plug change for your car? First real misfire of
any kind during your ownership? They err GM says our plugs should be.... good for 100K before changing them out, but
that seems to long of a time before a close inspection of what the plugs do look like after so many years of wear and tear.
IF it ain't broke don't mess with it...
I have read, heard other car shows guru's that when changing the plugs on your car, you should change the coil packs too
at the same time. IF neither of these has been done, since it left the factory, then it might be time for this change regardless
of the water intrusion, misfire you now have. Piece of mind down the road, from this point forward on the odo count.
Not fitting correctly when installed, is a new one I think here on the forum. Seated and flush to the opening before tightening
for each one? Some might fit fine, and others not so much. With no photos I could find on this problem, maybe an introduction
to this with a detail description of what we owners are looking for concerning your troubles here? I know for a fact my plugs and coils
are OEM, have not been changed from the factory or during my ownership. Might be time to take a look at mine now.
Cost is relative to usage. For under appox. $ 150. and hour or more, depending on adult beverages consumed during this process is not too bad, after years of wear and tear.
My other suggestion here: Stay away from big puddles when driving your Kappa.
