Re: Mazda 5 2.0 loose power when i accelerate, why?
Could be lack of fuel pump pressure. Check your pressure to see if it drops under acceleration. If it does, check fuel filter. If filter is new then it could be pressure regulator or pump.
Thanks for your help but I haven't change the petrol filter since I bought the car.Thanks for your help but I haven't change the petrol filter since I bought the car.

hi,
it could be lots of things like fuel filter/pump, coil pack.
inspect all vacuum lines. take it to autozone or parts store
for a free diagnosis so your not spending money on the wrong part.
You are a front wheel drive all traction is in the front,either you are overeving which is a transmission slip,if you say you loose power when accelerating you are describing a plug air filter and even a plug catalytic
The symptoms indicate a faulty MAP (manifold absolute pressure) sensor is not working as it should. Have the stored error codes read at a Mazda dealership or Autozone store. If the code comes back P0105 (or very close) this indicates faulty MAP sensor performance.
You may have a blown piston ring, valve seals, valve guides, cracked head gasket or a cracked block, etc... It sounds major though for you to lose power suddenly and have all that smoke...
