Re: Changed spark plugs yesterday, now I'm getting a burning smell (??
No, I don't think it is "new spark plug smell". As other have mentioned, check your wires to make sure that a wire, or boot, is getting fried by the headers. All headers, even the "good" ones will come very close to the spark plugs in some of the cylinders. Also, your new plugs may be slightly longer than the ones they are replacing. Care must be taken and as other have mentioned too, it is always a good idea to check the resistance in the wires when changing plugs.
