What is the gap on (A) old plugs and (B) new plugs ?
The replacement plugs should have been gapped properly straight from the box.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?
Is this required when installing new plugs every time?I would try resetting, starting with Idle Air Volume:
No. I only suggested it because of the misfire at idle. If the gap on the old plugs was worn to substantially greater than spec, maybe the computer leaned out the idle mix too much for new plugs with a narrower gap.Is this required when installing new plugs every time?
