Fuel filter, fuel pump, fuel pressure regulator, Idle air control valve, mass air flow sensor, faulty plugs, faulty injectors. If there is any codes set that is where I would start. The check engine light code is going to tell you somewhat what is going on. There are too many different things that there can be. My guess is mass air flow sensor or something with the fuel.

  • 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

I got the code from the OBD IT read a code of 23 and one of 36 now i need to find what it means

code 23 is MAT too low.(mass air temp.) code 36 is Mass Air Flow Sensor Error

The ECM receives a signal from the Mass Air Flow sensor depending on the amount of air entering the engine. The ECM uses information from this sensor to help calculate fuel delivery and spark timing.

Fault Code Description

  • 36 - Mass Air Flow sensor error


    • Engine stalling
    • Lack of power

    Common Problems Faulty Mass Air Flow sensor,Broken wire to Mass Air Flow sensor,Dirty sensing element in Mass Air Flow sensor

      99 Eclipse 2.4 cid idles erratically and eventually stalls. Unplug the air flow meter and idle quality gets much better and does not stall. Does this mean I have a defective air flow meter? Engine codes...

      couple of possible problems

      first thing i would check is to make sure air intake hose between Mass air flow sensor and intake doesn't have any cracks holes make sure clamps are tight

      secondly check for vacuum leaks carb cleaner works great for this spray around intake gaskets throttle body fuel injectors vacuum lines when spraying u notice change in idle (if idle picks up or stubles) that where your problem is example you spray around intake gasket and idle picks up you have bad intake gasket

      third thing is to try and clean the mass air flow sensor they make special cleaner for this (u can use carb cleaner for this but it can leave residue on sensor and damage it so it not recomended)

      my best guess for you with all three o codes is you have a vacuum leak somewhere

      My saab 93 showed error code P0100. I renewed the mass flow sensor but the error code and the poor performance is still there. the revs are limited to approx 3500.

      P0100 OBD-II Trouble Code

      Technical Description

      Mass Air Flow (MAF) Circuit Malfunction

      Basically this means that there's a problem with the Mass Air Flow (MAF) sensor or circuit.

      You will likely not notice any serious driving problems, but there may be symptoms like a general decrease in power or sluggishness.

      A code P0100 may mean one or more of the following:

      * The MAF may be disconnected, or a wiring connection may be bad.
      * The MAF sensor may be faulty.

      Possible Solutions

      Use an OBD II Reader (or go tou your local parts store and they will for free) and reset the code and see if it comes back.
      Then start with the cheapest, easiest repair procedures:

      * Check the Mass Air Flow Sensor wiring/harness is connected properly and that there are no broken / frayed wires.
      * Unplug and reconnect the MAF wiring harness a few times to clear the contacts.
      * Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information).
      * Replace the MAF sensor.

      Hello, Saab 2001 93 with trouble code P1181. It seems to be running fine and the light has not returned. Can you point me in the correct direction? ThanksJeff

      P1181 says Long term fuel Trim Additive, Max value, Air/Fuel too Lean

      Check for vacuum leaks, check mass air flow sensor if this is ok - check fuel supply (pump, pressure)
