if the clip on the connector to the spark plug is fine, then it could be pressure building up. the only way pressure is getting in there is if the spark plug isnt installed properly or it is faulty and pressure from the combustion chamber is seeping in there. get a ratchet and the proper socket to fit on the spark plug and see if you can tighten it down alittle more. dont go crazy with it though, its not ment to be torqued down hard like other bolts.
for the stuttering/stalling, check the AIV removal/cleaning sticky, and check the idle control valve (alittle hard to get to). those are your two most likely culprits
