My new 4cylinder matiz hunts badly between 1800 and 2000 RPM. Does anyone else have this problem or does anyone have any suggestions? My brother in law has an identical car with the same problem.Any suggestions welcome to, Will the Duck

Petrol isnt "ingredient" consistant! Every car's ECU will fine tune adjust to meet the programmed values

If it is a "new" fault then it's down to Air Flow or Electrical Shorting/Resistance!

I have a new engine in my Matiz and even that "Hunts"! yet it runs perfectly except for the MPG due to a Garage (Not FRF!!!) adjusting the ECU when the old engine was in the car.

All...

  6. Replacing fuel filter Matiz

    Matiz
    Hello people, What is the correct procedure for putting on a new fuel filter. I guess the fuel filter on our Matiz is about 15 years old 😅 First taking out the fuse of the fuel pump? Letting the engine run till it stops. Replacing the filter, fuse back in and ready? Thanks
