Hi

Does this only happen once the engine has warmed up? if so, does the truck accelerate if you put your foot to the boards? If so then have the O2 sensor checked out.

Otherwise, have the fuel pressure checked out, it sounds like it may be a wee bit low.

Regards

Geordie

    After thought!!!!

    Thinking about it, starting then stalling is a sign of a faulty airflow sensor. The signal from the sensor is generally ignored until the engine has fired up, then the problems occur.

I would start with cleaning the idle air control, then would clean the mass air flow. Also check the air filter. I have ran into oil soaked air filters on the Focus.

Where is the map sensor located


I don't list a map sensor for that model.
I do list a MASS sensor which measures air flow between the air filter and the throttle body.

I have a 98 VW Golf (ABA engine) it keeps stalling at idle. I saw that it might be the mass air flow sensor, so I unplugged it and it smoothed out and ran great. I replaced the sensor and it still stalls....


Try cleaning throttle body with throttle body cleaning fluid. You can pick this up at any auto supply depot. Just follow the instructions on the spray.

When was the last tune-up?

Inspect few plugs for carbon ash (lean running) or wet (rich running).

Clean Mass Air Flow sensor with CRC Mass Air Flow Sensor cleaner

Change air filter

Change PCV valve (under $10 item)

Ran a tank of Chevron gas with LUCAS fuel system cleaner additive.


Inspect for vacuum leak.
Start from the brake booster (round metal drum) and work you way outward.

clean the MAF sensor heated wires inside MAF with carb cleaner gently with a toothbush first. Then disconnect battery for 1 hour and reconnect and drive for 10 miles so computer can relearn clean MAF sensor.

Mass Air Flow (MAF) Sensor The mass air flow sensor (MAF sensor) (12B579) :
  • is located between the engine air cleaner (ACL) (9600) and the throttle body (9E926) .
  • uses a hot wire sensing element to measure the amount of air entering the engine. Air passing over the hot wire causes it to cool.
  • sends an analog voltage signal to the powertrain control module (PCM) (12A650) to determine the intake air mass. The powertrain control module will then calculate the required fuel injector pulse width in order to provide the desired air/fuel ratio.
The mass air flow sensor hot wire sensing element and housing are calibrated as a unit and must be serviced as a complete assembly.

It uses too much fuel. 2,6 liter per 10 km.


You need to replace the sensors,,Throttle PositioningSensor, OXYGEN sensors, Mass Air Flow. after which your truck will run nicer and use less fuel.

Hi,verify throttle cable is ok and connection at throttle body is good.If cable is ok,you need to do diagnostics on the computer..Every thing is speculation without data from computer.But i would check the throttle position sensor and the mass air flow sensor.Sometimes the maf sensors elements get dirty and cant read the correct amount of air flow entering engine.If this is the case,you can clean the elements with brake clean...Good Luck!!!
