February 7, 201313 yr If you removed the air cleaner cover, if it is not seated properly it can make a variety of odd noises.
February 7, 201313 yr Author yes I did remove it. and I think its settingin their ok. is there a way to tell if it is the' air cleaner. ?
February 7, 201313 yr 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

February 7, 201313 yr Author 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 just following the manufacturer's maintenance schedule. besides that when I pulled out they look pretty nasty.
February 7, 201313 yr Author 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.
February 8, 201313 yr 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. Sam
