Just tighten it down, don't over do it . Your problem may be in a different area. I would say your problem may be in the coils not having good contact with the plugs. This could happen, and your computer may not show a code , you could also have bad plugs. I would change the spark plugs, use some electric grease in the boots, and see what happens. GOOD LUCK FRIEND
