Reviews of Vehicle Emissions Testing in New Hampshire

I've flunked emissions on my wife car!!! Two years ago, the front catl convertor on my 2000 toyota camery was replaced?? both oxygen sensors were replaced, now this year the rear cat is being replaced and is still after a week in the shop!!! I don't understand what is taking so long!!

I personally feel these emission rules were made to help the automotive industry in NH, plus give more money to the state?? I'm up to $ 675.00 Dave's Auto on Main st in Manchester!! I have never had this kind of problem before with him!! Over a week, and don't have my car back???

He is not waiting for parts and the car is being worked on?????? I am on oxygen 24/7, on ss with disability, and find, we in NH are being cheated!!! Pick the highest price emission parts to replace, and still it may not be the problem??? We the public have no way of knowing who can do the repairs right!!

Can't trust the dealer, for they are very overpriced!! The State says emissions must work properly, which I can understand, but I say we are at the mercy of repair shops as well as at the mercy of the dealers??? State of NH inspection system is not fair to the public!!

I do believe in Safety, but these emissions testings are not fair to the public!!! Most places, who work on vheicles, are guessing as to what is wrong with emmissions??? That is very costly!!! Thank you for your time!!

Greetings David; there is no need for guessing on emissions testing. A qualified repair facility can diagnose and repair all problems when they have the right equipment. The problem today is that auto repair shops are not telling consumers that they cannot diagnose it properly. I am a service writer at Redman's Muffler & Automotive on Maple street in Manchester. If you have any questions I would be happy to answer them for you our number here is 603-626-1400. Hope you get your car back soon.

I have a 2000 Toyota Camry. Car runs great. Took it in for inspection and it failed emissions. I have ( since June ) fixed evap canisters, O2 sensor, some other exhaust vapor recirculator BS, all to a tune of $1400. Its now end of Aug, check engine light is now on and car is still not inspected. This is a joke. Especially frustrating when I am at a light and some giant POS car that sounds like its ready to explode has a nice fresh green inspection sticker on it. I could care less I gain an extra 5 miles per tank. NH only agreed to start enforcing this bad because the feds agreed to give them Highway $ contingent on them enforcing regs. Pretty soon state and federal government will start regulating tomato consumption per household because of excess farts burning a hole in the Ozone. This is bad top to bottom.

You realize they do the emissions test by a computer they hook up and it tells you exactly what is failing right?

and you realize the computer is sometimes wrong right?

And you realize that this is a big part of the problem...right? Computers making mistakes? Mechanics not knowing how to properly use the equipment? Lets change the system to a fool proof operating model. I do have to say that I rather get ripped off inNH than by the scumbags in MA.

I just want to know why my vehicle has to fail the EMISSIONS test, when all that comes up is a TRANSMISSION code. Transmission codes should have absolutely nothing to do with emissions.
