hoping somone can help. my 2005 Titan reached 100,000 i decided it should get new plugs. i purchased autolite irridium plugs (thats all that i had the money for), gapped them properly (wire gague and no i did not snap off any tips) and now i get mini misfires at idle. it just kind of stumbles randomly here and there but only at idle. I thought maybee i gapped one plug wrong so i pulled them and gapped them again to no avail. i am not getting ant CEL lite or codes. any ideas?

The replacement plugs should have been gapped properly straight from the box.

Double check the last two plug wires to the rear on both sides of the engine.. Manage to crisscross 'em when I did mine, with similar results.. Did it twice..:huh:

Also, make sure the plugs are torqued correctly. Some could be in further, or not enough, than other ones. Check that the wires are on nice and tight. Even though you bolted them down, they still may be a little loose. Plus what everyone else said.

I'm fairly certain that they shouldve come properly spaced. I bet that's part of the problem. Maybe its a corrosion/connection issue between the plug and the plug's rubber boot? Did you use any dielectric grease?
