    Start with a tune up . Are their any codes or service engine light showing? If so go too the liburary and research find out what the codes say it is. Retake the test.

    its not that cut and dried. there are several possibilities but most of them are related to egr or engine temp. does the car have good heat, does it warm up quickly ? Do you have a check engine light on ? What engine is in the car

    I have a Ford 2002 Explorer that has failed the Ohio emission test. The CO levels are very high. What would cause this problems and how can I correct it? The Explorer idle is running rough.

The most likely cause of this is a faulty exhuast recirculation system.It is used to cool the combustion process preventing the formation of nitrous oxide emissions. The main building block of acidic rain.Use your emission diagram and locate the EGR valve.You will need specialized equipment to check it. Other than taking it off and checking for blocked passages from carbon build up there is little you can do yourself.

I would check the catalytic converter to make sure it is not plugged or leaking.

What is the function or the egr on a 1995 chevy lumina 3.1


The EGR valve reduces Oxides of Nitrogen in emissions caused by high high combustion chamber temps. EGR allows small amounts of exaust into combustion chamber. This dilutes fuel air mixture cooling combustion chamber

Failing emissions testing due to high NOX (oxides of nitrogen)


I have seen several people posting emissions failures due to high NOX (oxides of nitrogen). Nox is created when the engine's internal combustion temperature gets to high.

Two reasons this can occur is improper coolant levels and a malfunctioning egr system. The egr system injects exhaust gas from the exhaust and uses it to line the cylinder walls.This in turn reduces the combustion chamber size and internal combustion temperatures. Ultimately this reduces the amount of NOX created. These systems functioning properly can be the difference in passing or failing your emissions testing because of high NOX ppm.

Not passing emissions


The NOx (Oxide of Nitrogen) level standard in the state of New Jersey is 1372. Anything higher than this number will fail emissions.

Had emissions test on '95 nissan 200sx. No check


hi try changing the spark plugs and air filter, these help immensely with the burning of fuel, also ( i don't know what you have in the US ) but use some redX to clean your injectors, this will also help....hope this helps

Vehicle takes 5 minutes to idle by itself. Why?


An inadequate functioning egr system.The exhaust gas recirculation valve uses spent exhaust gases to line the cylinder walls with burnt gases.The purpose of this is to keep the cylinder temperature lower to reduce emissions of oxides of nitrogen.

Improper fuel combustion; need to pass emissions test


Sounds like you need to replace your oxygen sensors.  If you have a four cylinder I think you only have one oxygen sensor and the six cylinder I know has 2.  You can check that out at your local parts store.  Anyway, the oxygen sensor helps the computers in your car make sure that you are getting the correct amount of fuel and air during combustion thus controlling your emissions.  I would think that if you haven't replace these in a while that is what is probably keeping you from passing your test.  Change the oxygen sensors and put a bottle of good fuel injector cleaner in a full tank of gas and you should be good to go.  I would suggest Greased Lightening fuel injector cleaner that can be purchased at Napa and O'Reilley Auto Parts.  Let me know if you have any other questions.  Thanks for an honest rating and for using FixYa!

Catalytic converter problem? Usually it takes most of the harmful impurities out before leaving your exaust system. $

high hydrocarbons indicates head gasket(1 or both) leaking , carbon monoxide is a worn out catylitic convertor which both could lead to the oxy sensor getting a false reading
