SOURCE: engine looses power going up hill, no check engine light at this time.

How old is the Catalytic Converter, sometimes they will get clogged up and affect performance.
Good luck

SOURCE: O2 check engine light

U may indeed have a faulty MAF or O2 sensor, the way to tell if the MAF or a vacuum leak is at issue is that both O2's will code lean, if only one codes lean then it is most likely just a faulty O2 sensor, I don't have your codes but this is the way we do things at the dealer for problems like yours. Remember the O2's are before the Cat's., after the Cat's they are called Cat efficiency monitors in the book.

dont look for air when the car cuts out its most likley spark or fuel when it cuts out ranomly its usually a sensor or relay that is faulty check fuel pump relay and camshaft or crankshaft sensors but first narrow it down to spark or fuel if possible also if check engine lite is on check codes

    1st have you replaced the O2 sensor? Here is the technical stuff about this fault code
    OBD 2 fault code P0171 VOLKSWAGEN - Fuel control System To lean engine cylinder bank number #1.
    Possible causes:
    Possible causes- Intake air leaks, spray propane around the intake manifold gasket and all vacuum connections and listen for a change in the engine idle speeds, any change indicates a leak.
    - Faulty front heated oxygen sensor (a common cause if the car has over 50,000 miles on it)
    - Ignition misfiring
    - Faulty fuel injectors
    - Exhaust gas leaks
    - Incorrect fuel pressure Hook up a fuel gauge and make sure the fuel pressure is good/in specs under a load.
    - Faulty Mass Air Flow (MAF) sensor
    - Incorrect Positive Crankcase Ventilation (PCV) hose connection

    Having the same problem on a 2005 4.3l....... replaced plugs, dist. cap, coils, and cam sensor. o2 sensor is good. idles great till you push the gas, then it misfires. timing was checked it was fine. ...

    Something is probably leaning out the mixture when you open the throttle. It seems that any ignition issues have been ruled out.

    So, check the following: fuel filter clogged, low fuel pump pressure, the fuel pressure regulator could be stuck at the idle setting, the EGR valve could be stuck open, faulty throttle position sensor (TPS) or circuit, faulty manifold absolute pressure (MAP) sensor, faulty or dirty manifold air flow (MAF) sensor, faulty intake air temperature (IAT) sensor, and an air leak into the intake duct or manifold between the MAF and the throttle body. I think if the intake manifold gasket had a leak, it would be misfiring at idle.

    Ask the shop if any of the above checks have already been accomplished. I'll bet most of them have, but one may have been overlooked.

    Po108 service code

    OBD II Fault Code
    • OBD II P0108
    Fault Code Definition
    The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Power Train Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems. The Manifold Absolute Pressure/Barometric Pressure Sensor converts the Intake Manifold air pressure into a voltage that is high when the Intake Manifold air pressure is high and low when the Intake Manifold air pressure drops to a vacuum. The P0108 code indicates a high voltage input from the Manifold Absolute Pressure Sensor/Barometric Pressure Sensor to the Power Train Control Module.
    • Check Engine Light will illuminate
    • In many cases, no abnormal symptoms may be noticed
    • In some cases, the engine may be hard starting and/or get poor fuel economy
    • In some cases, noticeably poor engine performance may occur
    Common Problems That Trigger the P0108 Code
    • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is defective
    • Intake Manifold vacuum leaks
    • Faulty or corroded Manifold Absolute Pressure Sensor/Barometric Pressure wiring or connections
    Common Misdiagnoses
    • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is an Intake Manifold vacuum leak
    • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is a stuck-open EGR Valve
    • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real problem is a defective Idle Air Control Motor, which causes a very low engine idle

    I have a 2007 chevrolet avalanche LT and everytime im driving it after a couple kms it will say low oil pressure turn off engine????

    Hello: What weight oil is in the engine? How many miles since last oil change? How many miles on truck? The first thing you could do is replace the oil pressure sensor. You will have to remove the intake manifold to gain access to the oil pressure sensor. If the engine is not knocking or there isn't any valve train noise then it could be the oil pressure sensor when this message is displayed.

    My 95 cavalier Z24 starts but cuts off after 1 min.

    Code P0108 is a MAP (manifold absolute pressure) sensor error.

    It is either mounter directly on the intake manifold, or on the firewall.

    If it is on the intake, the o-ring may have failed.

    If it is on the firewall, the rubber vacuum hose may have dry rotted or just have fallen off from either the sensor, or the intake manifold vacuum fitting.

    The sensors themselves very rarely fail.

    Your sensor will look like one of these:
