Hello, everyone. After servicing the engine and the combustion chamber from my Matiz 2002, the vehicle started accelerating and decelerating by itself. After scanning it, I was told the MAP and TPS sensors were damaged. I replaced both of them and the car started burning spark plugs and losing power. I was then told it was the oxygen sensor, so I bought this sensor and the IAC as well in order to have all the sensors new. But things got worse because the vehicle does not even start working now. Occasionally, some combustion noises are heard and the vehicle starts and immediately stalls. Spark plugs are always wet with fuel. I've already changed the distributor cap, the rotor and the spark plugs wiring, but nothing got better.
