    emission wiz

    So are you saying it is not worth the air filter change. i need to go to the mechanic and ask him to look at the 02 sensors. and about how expensive can that be?

  • suziesaysr Nov 04, 2008

    Ok could you come to Arizona and fix this problem. i know my mechanic said it could cost up to 600.

    what happens if i dont change this will it ruin my transmision?

  • suziesaysr Nov 04, 2008

    The air filter will not turn on the check engine light, I did emission work for 20 years in a new car dealer, how much will it cost, well about $200-400 depending on what they find, if a O2 sensor is the problem around $200

Yes, worth changing the air filter. Had the same problem recently and that cured it (are your having hesitation at startup, by any chance?). If not, could be the oxygen sensors. It's worth dealing with this sooner rather than later -- it's probably decreasing your mileage.

2003 Nissan Altima 2.5L Service Engine Soon Light is on, Auto Zone says codes are for MAF and O2 Sensors. Car hard to start after driving a while but when starts appears to run smooth. Auto Zone thi

ok lets start with the codes they say your getting. P??? which 1's and how many. there are few o2 sensors, are they next to the Exhaust next to the converter? MASS AIR FLOW -MAF use this, for now i am guessing, until i see the correct codes your are getting. this could be the 1 you may have below, please read it........
  • P0103
    Mass Air Flow Sensor Circuit High Input
  • Possible causes
  • Faulty mass air flow sensor
    - Intake air leaks
    - Dirty mass air flow sensor
    - Dirty mass air filter
    - Mass air flow sensor harness is open or shorted
    - Mass air flow sensor circuit poor electrical connection
  • Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
  • possible symptoms Engine Light ON (or Service Engine Soon Warning Light)
    - Engine stall
    - Engine running rough
    - Excessive fuel consumption
    - Excessive smoke
  • the code is generated when An excessively high voltage from the sensor is sent to Engine Control Module (ECM).

I have 1998 Pontiac Bonneville 6 cylinder, I went Advance Auto because my check engine light came on and they told me it was PO171,Bank one system too lean. Yesterday, I use Seafoam and flush the fuel...

chances are the 02sensor needs replacing,the bank 1 is the exhaust system that cylinder 1 is on the motor and is threaded in the exhaust system.

I have a 2001 Jimmy with "Service Engine Soon"

P0171 System too lean bank 1
P0174 System too lean bank 2

Last time you changed your fuel filter?
Look for any vacuum leaks.

P0171 just replaced mass air flow

p0171 is system to lean ( bank 1 ). did you turn off check engine light with a scanner! if not go to auto-zone and they will erase it for free, then you can see if light stays off. There could be a vacuum leak downstream of the MAF sensor.
  • Inspect all vacuum and PCV hoses, replace if necessary
  • Check for a dirty fuel filter and proper fuel pressure. Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1. good-day!!

    I have a 1999 chevy malibu - 45000 mi. Took to auto zone for computer reading and replaced O2 sensor that the dealer replaced with the fuel filter. about 145 miles while accelerating up a moderate hill...

    The 02 sensor is detecting a malfunction in the emissions. That would be from a bad fuel mixture, too rich or too lean caused by dirty or faulty injectors or MAF sensor. A clogged catalytic converter will also cause it. Connect a manual fuel gauge to the fuel rail and test your fuel presuure. Test your fuel pressure regulator, the fuel pressure should increase 5-10 pounds when you disconnect the regulator...if it don't, the regulator is bad...Check for vacuum leaks and stuck or dirty egr valve. This would cause a lean condition. Check your air filter. Good luck, i hope this helps.

    What does it mean when your bank 1 n bank 2 are running lean

    A lean bank 1 and 2 is indicating there is not enough fuel being injected to support proper combustion.
    Leading causes can include but are not limited to......
    1) low fuel pressure or plugged fuel filter.
    2) vacuum leak causing lean condition.
    3) air intake hose or crank case not sealed properly and bypassing the MAF sensor or the MAF sensor element is dirty.
    4) wrong fuel or poor quality fuel used.
    Hope this helps. If the Service Engine Soon light is illuminated, there will be fault codes associated the light. Get the vehicle scanned for free at your local Auto Zone or Advanced Auto and report back.
