High CO means incomplete burning of fuel, and/or rich mixture condition. If all else has been done correctly, I'd be leaning toward a fault in the EGR system. If it's been scanned for trouble codes lately, then possibly that may have come up, but if not, I'd have it scanned just for sure. Your local autoparts supplier should be able to tell you if the possibility of using a hotter plug is possible, which also may be a quick fix.Perhaps another expert "emissionwiz" could add some expert advice to this posting.

Why wont pass emmissions. have changed spark plugs and filter. they say my hc readings are too high and also the co readings


Any codes present? Is your car a daily driver or has it sat for extended period of time? (hence how old is your gas? ) Is this car new to you or have you had it for a while?

I have 1993 pontiac bonnevile, it will not pass emissions the nox levels are to high this is the fourth try. what can i do. also my check engine light comes on as well.


high NOX indicates your engine is running high combustion temps. Two of the major reasons for lean mixtures are intake leaks and clogged fuel injectors. The reason the engine computer cycles between rich/lean when running is because the cat needs lean mixtures to deal with HC and CO and a rich mixture to deal with NOX. If you are running lean the cat can't lower your NOX. I would first get your fuel injectors flushed and de-carbonize your intake/combustion chambers.

Emissions failing due to high nox


NOx emissions are the result of high combustion chamber temps pure and simple. NOx readings go up whenever there are hot spots that exceed about 2400 degrees. Things like lean mixtures contribute to high chamber temps, as does over-advanced ignition timing.Lean mixtures are usually caused by some failed components or by air (vacuum) leaks in the intake.
Poor fuel quality contributes to detonation, another cause of high chamber temps.
  1. Check to make sure the vacuum system is tight.
  2. Try a full tank of high octane fuel(run at least half a tank through before testing)
  3. Have the tester do the rolling tests with the trans locked in first gear.
  4. Make sure the oxygen sensors is working.
If you have done all of this and still fail, You will need a new catalyst

Can't turn the idle down


you have 2 idle settings. one is for cold and one is for after the engine has warmed up. So find the scew that goes to the warm engine idle. turn it down and your set. You might need a Chilton to find what you are looking for.

1991 Camry running rich


check for vacuum leaks especially around the intake manifold gasket. Although the engine appears to be running rich, it could also be misfiring due to being too lean in one cylinder. When the cylinder doesn't fire the charge, it goes into the exhaust completely unburned and looks like a rich running condition due to the unburned fuel. If it is a vacuum leak causing the problem, the engine will run fine at road speeds but misfire at idle and not pass smog.

I have a 1997 grand prix and it wont start.


Start with the Cheaper Fix First. Change the Fuel Filter and Get the Fuel Pump Checked for Preasure. That Timing belt is a Big job and you will need to reset the Timing which can be Very Difficult. Did it run Smooth Before???? If so the Timing belt is Probably Fine anyway.
