Q: the problem with just the sniff test is that it requires people to be honest and actually care and unfortunantly that is something that fewer and fewer people are these days. the sniff test tells exactly whats coming out the tailpipe. yea at that particular time which with a little creative tuning has nothing to do with what is normally comming out of the tailpipe every other day of the year. no honesty factor about it the engine cannot burn what is not there. really it can be temporarily tuned to burn fuel far more efficiently than it actually does under normal conditions which is dishonest now isnt it if you are worried that someone will modify after being checked with a sniffer all the other tests and inspections suffer the same flaw. i am not worried about it but it does happen and while it can still happen with many of the current inspections many of the more recent ones make it much more difficult to do especially the odbii one. at least with the sniff test we know the car is meeting the emissions regs not just looking like it will. it means no such thing unless of course the person owning the car is honest and brings the car for inspection tuned the way it is the rest of the time. gee there is that honesty thing again. -- if at first you dont succeed youre not cut out for skydiving .
