RENAULT ESPACE II MATRA MOTOR OF 1996

Dear friends I have bought a Espace of 96 Gasoline Matra Motor 2.2, the man who sold it to me says that he has a valve that goes in the broken escape, the problem is that the engine has little power does not revolutionize much, it has a small loss by the exhaust collectors, you have firecrackers in the engine when strength is asked, it consumes a lot Carbonilla in the soil. How can I solve this. She scores well to the first key roll but if at 20 seconds, I slow down, a lot of consumption, 40 euros in 170 kilometers. The needle is seen down, I wanted a orientation before taking it to the workshop.

From what you say you have to get the cylinder head to perform a decarbonization, and see why the ex -fuel excess in combustion, because that is what happens to you, but you have to start by measuring compression to see why it says it has a burned valve and if it is true or has problems with set -up or the injection system.

Thank you friend for your answer I will take you to the workshop to look at the compression, I will change spark plugs and filter that I do not know when it was done the last time, and see that the machine says, it can be because it has a lot of a bad adjustment of valves or a wear of the docks?, because it does not consume water or oil, nor heat up. all the best. And thanks
