When I bought my NSX three years ago the owner said he just had the Plugs changed so I took his word for it and never noticed anything strange until this year. After getting the car out from winter storage I noticed it running bad always killed on the first start had a backfire at idle etc. Well today I decided to change the Plugs for the heck of it and man they looked terrible take a look at these...I only put on 4,000 miles a year so if they were changed this is what 12,000 miles does to them? Has anyone changed there Plugs and did they ever look that bad. The car now is totally smooth starts and does not kill and no backfire man what a difference.
