Accelerated slowdown, lack of power.

Hello, good I have a 2000 Renault Laguna. I gasoline is 1995.The engine is fine, but it lacks power, the slowdown is up Map sensor, for the rest he sees it well but I don't know. I await your answer. Thank you very happy new year

This question gives me the opportunity to insist that modern cars must be inspected and repaired by specialized personnel.
A refrigerant sensor failure will never offer a failure like the one you mention,
that failure can be caused by a minimum engine malfunction, I recommend lowering it to clean it and re -install it and check the connector very well to it very well

Jo Colega If you are cracked, what do you think? Is it beautiful? I recommend looking at the Starter and from that point controls whether it has a sensor or mechanical action failure, a car accelerates when you receive a lot

Well, actually the rise in revolutions is by much air more than fuel, but you should check the proper functioning of the Relay Actuator and do not have false air tickets
