Renault Twingo

Hello, I have a 2003 Twingo that has been presenting a fault, as if all cylinders did not work, it is weak and trembling. The mechanic tells me that it can be the coil or else, in the worst case, the computer.

Could someone give me your opinion?

A couple of weeks ago they changed the avionncito (or pig) and cleaned the injectors thinking that this could be the problem ... In fact he took off his fault for 2 weeks and appeared suddenly again

thanks thanks

If the engine heads as if it were in three cylinders it can also be sparkling failure in spark plugs, the way to check is to start the car and disconnect spark plug by spark plug. If when the engine is discouraged, it stops again and tests with the Sigante. If when the engine is disconnected, I do not stop and continue to head that cylinder does not work so it can be the spark plug or cable

Look that it could be the distributor's lid if it brings and the rotor that is throwing the spark for the other side, does not consume water, but could also be the injector that was dripping, it could be some hose that of the TBN brake serve or some hose of the base of the butterfly that you are cracked or to break

Well, buy the coil to see if that is the problem ... Tomorrow I tell you ... I just hope it is not the computer!

Do not worry is not the computer if this fault there is no spark in any of the cylinders or there is no injection in any of the injectors, the computer does not fail by cylinders but the entire system, the checar of the checar that silhindro is the Ke fails to ahislar the problem, and then see Porke does it if it cuts the current or the spark, or this evil of rings etc.
