I moved here in '03 and have'nt had to go through an emissions test yet. I bought my Mach in '04 and my '05 Focus in '05, and I guess you are'nt supposed to get emissions checked for 5 years after you buy your car. If you just move here, maybe it might be 5 years after you move here also. Their trying to get Kommifornia laws in place here, but a guy awhile back posted in the NW section forum that he worked for the emissions dept. and he said the emissions law will never take effect and they have no money to implement anything. He seemed to think the emissions testing here would be scrapped all together in the near future. Their's no sniffer test here. They do check your computer through your OBD II so if you show no codes being thrown you should be golden. From what I've heard some places are jerks about exhaust decibel levels. They might bust you for that if it's too loud. That's really about all I know about the testing until I go through it myself, but not for another 2 years.
