we have a Daihatsu materia 2005 , we replaced the plugs,cam sensor , petrol pump, body sensor, air intake temp and catelis converter. The car drive fine when cold, but after a few kilometres it doesn’t accelerate when pushing the petrol pedal and sounds like it’s smothering.
Changed coil 1 and 4 , still the same. What else can be wrong?
Diagnostics say misfiring on all 4 cylinders.
Car only got 64000 km’s on. Fuel pressure 3.5
