Power loss

Hello everyone I need help, I have a 2005 K4M Renault Megane, for some time I notice that it is consuming me more fuel and as it is heavy as it has no reaction when accelerating as before, it is more notable to the mometo of an overpower, always terrible reaction tube and acceleration now is as vulgarly it is said (pig) to the reaction momet.

I thank you for a Monton for your time and I hope someone guides me to do.

Hello, Miñoca. The K4M are engines of phenomenal reaction, if the power loss symptom began gradually and does not have the witness witness on, the most caused thing is that the fuel filter is obstructed or the benzine pump is evil .... Anyway, it measures the fuel pressure in the rail. Eye also verifies that the car is not slowed down ... or can be in 3 cylinders because a pencil type coil failed, in this case, lost of smoothness of the engine, especially slowed down .... in addition to all of the above. A cordial greeting and luck from Chile. Tell us how it went.
