CNY_Dave Posted February 7, 2013 Share Posted February 7, 2013 If you removed the air cleaner cover, if it is not seated properly it can make a variety of odd noises. Quote Link to comment Share on other sites More sharing options...

GeneralDisorder Posted February 7, 2013 Share Posted February 7, 2013 The factory plugs are good for 90k. Why would you change them at 35k? Pretty much a waste of more than half their life. GD Quote Link to comment Share on other sites More sharing options...

GD just following the manufacturer's maintenance schedule. besides that when I pulled out they look pretty nasty. Quote Link to comment Share on other sites More sharing options...
anto5930 Posted February 7, 2013 Author Share Posted February 7, 2013 also I gaped them at .043. does that sound right? I was thinking maybe the noiset was because I didn't use a to.rque wrench so I estimated by feel. Quote Link to comment Share on other sites More sharing options...
somick Posted February 8, 2013 Share Posted February 8, 2013 The factory plugs are good for 90k. Why would you change them at 35k? Pretty much a waste of more than half their life. GD Factory recommended maintenance states - 30,000 miles. When I changed mine at 30000, the gap on the old ones was quite big. I have read somewhere that the coating on the plugs at this mileage has gone. OP. Do you hear the noise when driving or do you hear it only when idling? I was paranoid when I changed mine and kept listening to the sound as well. I also thought I heard something weird. I have 35,000 on mine now and do not hear anything strange anymore.
