kevin say something about gap the spark plug 40, and I did gap it 40, after done I test drive, take it to the highway, then come to stop, WOW no more jug around, idle normal ( well it happent before and my mechanic did the same thing , change spark plug and pour in a bottle of fuel injection cleaner). But I dont know gap 40 is good for NGK or not.

regardless of the plug's brand name, you should follow the gap recomendation made by the car's manufacturer. It's on a sticker on or under the hood, but on old cars it can be damaged or missing. Try the manual if you have it in that case. I don't know what it is off the top of my head for NTs unfortunately...
