Are Arizona emissions tests bogus?, test history makes me wonder... Options

[914GT]

I was bored with work and I was curious how the emissions test results compared going back over the years on one of my cars. I kept almost all the inspection results for an Acura Legend that I bought new in 1987. My daughter has been drivng this car the past few years, and I still maintain it. I picked this car as I know its history and I always maintained it well. Basically the 2.5L engine has had little done to it over the years, plug changes a couple times. Replaced and/or cleaned the injectors a couple of times. The usual routine filters, etc. It's never failed emissions. I replaced an O2 sensor once because the engine service light came on.

I don't see any rhyme or reason to the numbers. We'll see how it does next month when it's due. There are some screwy variations over the years that I can't correlate to any particular repair or maintenance item. Makes me suspicious of the whole thing. I'd expect some variation due to the car and testers (all at the same location) but there are some years that are drastically different.

Interesting. Who knows? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

A few years ago I was kicking around they idea of putting a 6 in my car(this was before I realized I would have been in WAY over my head) Any ways, my car being a 75, I assumed that there would be emmissions issues. So in my due diligence I called the DMV and started asking questions about what I would need to do to make it pass. They weren't really sure and suggetsed that I go talk to the superviser at the inspection station since he would have the info right in front of him. So I did. He fumbled around through the books and started giving me several half-assed answers. Basically no resolution. He had no clue. I went back a few weeks later after talking to some local shops and getting more info. This time there was a different guy. He had no idea either. He gave me a completely different set of answers.

Based on my experience there, I am convinced that if the numbers pass on their machines they would have no idea if the proper cats were installed, proper fuel system or anything. They would look at their charts and say, off you go! I say this because last time I went there they asked me to pop the front hood. I do so assuming they are checking the tank/gas cap...who knows. Then they guy says, "Oh yeah, I forgot the engine is in the back" Off he goes. I watch him for a second and finally pop the deck lid. "Thats cool. You have two trunks!"
