    Car boggs Down, and doesn't want to go over 30 mph

    Yo fellas,

    another issue...
    I ran a code test and need some clarification.
    Codes are

    44 AIR system inoperative - Air Injection (how can I find/repair)

    66 Vane Air Flow (VAF) or Mass Air Flow (MAF) signal low - VAF MAF
    Transmission Oil Temperature (TOT) signal low (possibly grounded) - Transmissions (where to locate the tranny oil temp sensor)

    22 MAP (vacuum) or BARO signal out of range - MAP(changed)

    54 Intake Air Temperature (IAT) or Vane Air Temperature (VAT) signal high - IAT VAT (changed before issue came up)

    Simptim...

    car at idle is abnormal , has a smooth, rough, smooth rough (continouis)

    while on drive (Shit...) she hesitates pretty bad and then goes but it goes from first gear to second gear at 10 mph, then second to third at 15 mph, third to forth at 25-30 mph. she doesnt sound like she's pre ignitioning or pinging. The tranny before these issues shifted fine, but now she shifts pretty rough, also when the gas pedal is fully pressed the engine revs high but there is no power to the wheels..(she shifts way to early)

    She may be starving of fuel... fuel pump might be bad, but a code didnt go off or pop up...(changed the fuel filter 6 months ago)

    Can a malfunctioning (signal low) MAF make the tranny act up and shift erracticlly?

    Any help would be appreshated
    thnx

    What's the condition of your TV bushing? This sounds an awful lot like a disconnected cable, and if that's the case, DO NOT drive it until you get it replaced.

      yeah... check that bushing... sounds like no TV pressure to me too.

      And what are you reading your codes with? you shouldn't have a trans temp sensor that Im aware of...
      Check your air intake tube between the MAF sensor and the throttle body - holes/cracks in that will let in un-metered air and will make it run funny.
      The air injection problem shouldn't affect how it drives...

        TV bushing looks normal, inspected it with engine off had brother step on gas to see if cable was loose. It wasn't, its actually pretty tight.

        "like a disconnected cable"
        if you mean the cable from the throttle body linkage to the tranny it appears connected from the throttle body area and down by the tranny.

        "Check your air intake tube between the MAF sensor and the throttle body"
        Checked and inspected no cracks or air seeping in ...

        dam fellas... she ran great before this started to happen...

            FUEL PUMP!!!!

            GOD DAM FUEL PUMP

            got it replaced... now she runs like a champ!

            fuel pump caused the car to bogg down in which i guess the car went into limp mode (my guess).
