emmission test, Maryland

Hey guys I just failed emmission test today .

I failed and I don't know what's the cause.  I failed the part called oxides of nitrogen ( something like that) . 

Can anybody tell me what should I do with this in order to pass the test?

mitsubishi eclipse 1995 GS

mod done :

02 sensor cheater installed on downstream rear o2 sensor.

Thanks

My guess would be the 02 sensor thing... but keep me informed... cuz I got cars that gotta pass MD inspection next month...

wtf do you mean by o2 cheater, and why do you have it? are you running catless?

It basically simulates the voltage of a perfectly find o2 sensor so it does not flip the ECU code. However if they actually test the exhaust then you will be ****ed

As I thought then... the sensor thing. What benefit does the O2 "trick" cause?

Once again i ask why then? because it doesnt seem like he has mods where he would need to do any tricking of the o2 sensor. Unless he is catless, which is just dumb.
 
I say get rid of the stupid o2 trick, then put the stock one back it, drive it around and re-test, if you still fail, then check your egr valve

Ya, the only thing that is doing is tricking your ecu from sending out a check engine code...   But in reality you arent ever gonna pass an emisions test...   Just b/c you trick your ecu doesnt mean its up to code 

True that on the tricking the ECU.  I almost pass the emmission.  Nox fail because I was 2.5#### and the passing point is 2.1####

someone told me to put 2 cans of dry gas , take off air filter and drive the car on highway for 20 minutes at least before the test

What do you guys think?    I have 4 months to come up with something.

Forgot to mention.  I still have my cat converter. 

What is egr valve? 

It is a valve that recirculates some air from the exhuast back into the engine (Exhuast Gas Recirculation Valve) Alot of times when the start to get clogged, or go bad you will start to see higher emmisions #'s. And i believe NOx is one that it would mess up. But you could also try the dry gas, that will reduce your #'s a bit

A friend of mine with oil leaks everywhere in his honda accord's engine got a worse reading than mine.

His first reading was 6.2##### and he went for the second time after using tons of gas treatment for 4 months and it went down to 4.3#####

I hope mine will work because I put that guarantee to pass emission liquid.  Since I put that liquid my car idle much and doesn't stink as much. 

another thing about Having Mitsubishi eclipse 1995,  At the emission test they don't care about the CEL because it's not required to get OBD test although my car uses OBDII port connector.  I think from now on I will just buy car 95 and below....

haha, i know, the same thing with my old one. I had a 95 AWD and still onlg got a smog test. Although i hear now that in 2008 in mass they may be doing away with smog testing. So i might not even need emmisions in my 91
 
I think that gas treatment should work

Dry gas, TE?

its just what its called. Its a gas that the way it burns it will reduce the emmisions slightly. Some places just call it the "guarenteed to pass emmisions gas"

Will it make up for a cleared cat?

how old is the car? If your on a 96+ then you dont have anything to worry about cuz you can fool the system on that one. But on a smog test i doubt it will make up for it

I never had to take a test when I got mine..  Which is a good thing b/c i would fail..   The 1 + with living in wisconsin...

Engineer. I see in your picture that you have toyota MR2.  HOw's that car?  Is it good for daily driving? Does it have a lot of mechanical problems?  I'm really bad in fixing my car so I'm looking for something reliable for my second car.

I love it, i havnt had it very long but from the time ive had it, its been fun to drive. Havnt really heard of too many mech. problems with them Higher mileage ones sometimes spin bearings, but thats mostly to people beating on them and building them up. and of course because of high mileage. But there are two engine types. The turbo (3s-gte) and the non turbo (5sfe) both are pretty reliable.

What's a good price for high miles like 120k and above?

is it hard to fix the speedometer problem?

the 92 non turbo is alittle high priced. I picked up my turbo with about the same miles for that price. Those generally go for under 5k. But the turbo model seems about right. The front bumper sucks but that would just be a good reason to get a 93+ lip. Im not sure how difficult the speedo is on these cars
