Need to identify which engine you have. Might not be related at all. Possibly ht leads shorting out if it's a DOHC

plugs are under the coils, about 200mm under the coils, down the deepest tightest hole you could even imagine a car engine having, and once you've got the coils off the fun starts take one of your prized sockets that will fit the plugs and grind the walls down until they are paper thin, then wrap the end of an extension bar in insul tape and jam the socket on, feed the socket down the hole until you hear a rattle - thats the socket falling off, shut the bonnet and go on holiday

get your magnetic probe and fish the socket out, it will come up as far as the head gasket, which is steel, and then drop off again, repeat until the cows come home, on their own, wagging their tails behind them put another 2 wraps of insul tape on the bar and drive it into the socket, jamming the now super thin socket that will have spread well down onto the plug hex, where it instantly becomes attached with the ferocity and determination to stay joined forever of a teenage girl in love for the first time, ie you now cannot get the bar, or the socket out

ah ha he cried, I only want to get the plug out - so grab a ratchet and ever so carefully, and very slowly, rip the socket in half - where you weakened it by grinding it, remember - and the plug is still as tight as a nuns cnut tow the car to a workshop stand in shame while the 4 mechanics, 2 apprentices, the office lady, and 2 passer by'rs laugh their tits off - should calm down after about 10 minutes or so, then standby for a shock when they tell you how much it is going to cost for them to fix the problem

go back 3 days later to pick the car up, and find the plugs were perfectly okay, but one of the coils had tracking down the inside of the replaceable stems due to moisture, and they show you the old stem with its white marks down the inside $18 for the stem, total job $455 ( they put new plugs in anyway while the old ones were out)

Surely there would be a box spanner in the car's original tool kit designed to fit the spark plugs? Or would that be expecting too much? (Glad we bought a Honda. )

some claim there was one in the original kit, I've yet to see one though
whip the cover off the top, remove each coil, unplug each coil, check each coil, being very fussy, then check them again, then get a very good torch and check down each plug hole, get a thin hose on the end of an air gun and blow out each hole, if any show signs of water keep blowing, and keep blowing, and keep blowing you can if you wish purchase a thinwall socket- be aware that not all thinwall sockets are thin enough, you then have the issue of getting the plug out of the hole after you have got it undone - and blow out all plug holes first I've actually repaired one that somehow dropped a couple of small stones into the piston crown, I suspect down through a plug hole when the plug was lifted out magnetic probe will lift the plug, not good for replacing the plug though, first drop closes the points etc

lol, the previous is the ramblings of a home mech doing his first 4G64, its good for a laugh, but seriously if you're intent on doing the job, check the coils first and foremost, they were prone to cracking and thus arcing and are replaceable, if they all show good and were dry then you may have to pull the plugs - as you can see this is akin to home eye surgery, with a blunt knife and a fork, and should only be done by masochists or those experienced in self harm

I welded a extension onto my socket for this very reason

Why are you pulling plugs? Water doesn't get into engine! Only need to remove coils and spray leads, connections etc.

taking all this info into account, and by what friends have told me, it does sound like shorting or damp ht leads and coil. im only used to 202's and 186's. looking under the bonnet is scarey stuff. would youtube help? ive seen quite a bit on there
