I have Fiat punto mk2b (2005) 1.2 8v. First the problem started when the car jerked sometimes and it once gave me the error code from the ignition cole. I replaced both ignition coils, spark plugs and cables. The car ran fine after this couple of weeks. Now it started to use more fuel when cold and the engine sales sometimes on idle when the motor is cold. It now gave me the error code p0130 and p0135. I cleaned the lambda sensors with electronic spray and after this it only gives me the code p0130 every time I start the engine. The other lambda was really dirty and black. Now the car runs sometimes fine and sometimes it sales little when the engine is cold. I also think it doesn't accelerate always so good anymore. I also checked the map sensor and it was little wet of some liquid (fuel maybe?).
So my questions are is it probable that I need to replace both lambda sensors or might it be the map sensor that is the problem? I know there is a tiny leak in the back of the exhaust pipe but I guess this couldn't cause this much problems since it has been there for awhile and the car has worked perfectly before.
