    Ford escape won't stay running
    My 2001 ford escape xlt 3.0 automatic stalls as soon as I start it.
    As soon as I let go of the key.
    I have to keep my foot on the gas to keep it going until it is warmed up .
    Then it runs fine.
    I have replaced all the spark plugs and ignition coils
    Two oxygen sensors and the rear catalytic converter but still no change.
    What could be wrong with it?
    Thanks

    I'd focus on the MAF Sensor and the Engine Coolant Temperature (ECT) Sensor. Best to stay away from remanufactured MAF Sensors and go with a Motorcraft. Check for codes and pending codes with an advanced scan tool.

    I have checked it out with the scan tool
    But it says ignition coils 1 and 3 are misfiring.
    I have already replaced them
    The last time it said the coils and 2 o2 sensors.
    Have replaced them and still the same
    Thanks

    Are you using the same Motorcraft spark plugs that came in the vehicle?

    Could it be the cat converters in the exhaust manifolds?

    If so, a code should definitely have been thrown.
