Try cleaning the EGR valve. That will DEFINATELY mess up your emissions test. :) Hope this helps. To clean it all you have to do is spray WD40 on it, and get ALL the carbon out of the valve. Your valve could be stuck. James Booth

    The 6 Smog Check Passing Tips - before you visit the smog test center!


    1. Running Right - Do not subject your vehicle to a Smog Inspection if it does not run right. Chances are that it will fail the smog check and you will lose your inspection fee. Seek repair assistance first. This will save you time and money, and insure your vehicle will pass the smog test.
    2. Take a Drive - Drive your vehicle for at least 20 minutes prior to arriving at the smog station. This will ensure your vehicle is properly warmed up and is running at it's optimum level. Remember your engine is a fuel burning machine. To ensure proper combustion it needs to have sufficient time to warm-up and this can be accomplished through driving for at least 10 to 15 miles.
    3. Use Additives - The use of fuel additives can be very helpful in lowering emission levels. Fuel additives are generally poured into a vehicle's gas tank during fuel refilling. The additive is mixed with ordinary fuel. The purpose is to clean carbon deposits within your engine's intake and exhaust paths, allowing for both fuel and air to flow freely within its passages, thus lowering emission levels and improving combustion, as well as overall engine performance. Additives offer helpful solutions to various vehicle emission and smog test problems.
    Note: Read the fuel additive's usage label regarding having your vehicle smog tested with the additive in the gas tank or after flushing the additive out.
    4. Inflate Tires - During the smog inspection, the smog technician may need to drive your vehicle on a dynamometer as a part of the smog test process. Making sure your vehicle's tire pressures are even and correct will allow the vehicle to be driven with greater stability and accuracy during the smog exam. This will improve the overall emissions output of your vehicle by allowing the engine to maintain a constant and steady load. Correct and even tire pressure may be the deciding factor between a borderline vehicle failing or passing the smog test.
    5. Change Oil - If it's close to your next oil change interval, go ahead and do it before the smog check. The PCV (positive crank ventilation) system of your vehicle is designed to allow your engine to breath fumes located in oil compartments (oil pan, ect.). The fumes are then burned through the combustion process. If the oil in your engine is contaminated due to inadequate oil changes it may very well cause your vehicle to fail the inspection.
    Contaminated oils are high in Hydrocarbons (HC) and will present a rich mixture to the engine chambers. Avoiding oil changes not only causes pre-mature engine wear but can also cause your vehicle to fail the smog inspection. Change the engine oil.
    6. Check Engine Light Off - Make sure your vehicle's Check Engine Light or Malfunction Indicator Lamp is not illuminated. A constantly illuminated Check Engine or MIL light is an automatic smog failure. A certified repair shop can diagnose the check engine light condition and offer you an evaluation and estimate. The home mechanic may also diagnose a Check Engine light malfunction via special Check Engine codes retrieval tools, available at most auto parts stores. Note: A smog technician can not refuse to test your vehicle based on the fact that he or she notices an illuminated light. The smog technician must perform the smog check and fail your vehicle. This is California State law. Be aware.

sounds dumb but here in maryland people with older vehicles have problems passing emissions test. sometimes fresh oil change can help also possibly vehicle is in need of a tune up including plugs wire cap rotor pcv valve and fuel filter. one other thing could be the catalyst converter might not be cleaning to its full potential. hope this helps

1986 NISSAN 300ZX FAILED EMISSIONS HIGH CO


I would replace CATalitic converter, this car is old, plus a tuneup is 100% necessary , spark plugs wires, ditributor cap & rotor, plus both the air & fuel filters need replaced. change oil & filter. then you will pass emissions test. and your car will run like its suppose too. if you don't do all this , then buy a new car !

Failed smog test


Most modern vehicles have 2 catalytic converters, there may be one located at the exhaust manifold, or be what's called a resonator. The resonator will look almost like a cherry bomb muffler, this is a crucial part of exhaust emissions.

Failed Smog Test - 4 codes for 2001 Isuzu Rodeo


Tune it up and replace the 02 sensor that keeps setting the codes bank 2 sensor 1. Have your oil and filter changed right before you go for a retest to. That will clear up 3 codes P0300, 0155 and 0154. You might have to replace the fuel sending unit to get rid of P0463 but if the gauge works OK I'd leave it alone.
