Hello, I have a big problem with my Matiz 2000. It is powerless and, at idle speed, once the normal working temperature is reached, revolutions raise and drop continuously, generating a low oil pressure. Even more, the car jerks considerably at any gear and both when cold or warm. In order to stop the jerking a little bit, I need to keep the clutch pressed more than usual, generating a disgusting burnt clutch smell. I've replaced everything already, including: cylinder head, valves, filters, fuel pump, sensors, TPS, IAC, spark plugs, wires, camshaft, timing belt, hoses, among many other things, but nothing got better. The car has got a good compression, around 160 pounds. I really do not know what else to do. Thanks in advance for any help you could give me.

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.

Hi, everyone. I have a Matiz 2001 and, three months ago, when I started the engine, it accelerated to 3000 rpm. In order to make them drop to 1000 rpm, I had to wait for around 30 seconds. I was told it was the MAP sensor that was failing, but I did not replace it. I disconnected the air intake and too much fuel started to get burnt, but revolutions stabilized. Three months later, the vehicle stalled in the middle of an avenue, and I was not able to start it again. I disassembled it and the combustion chamber and all the pistons were full of coal. In order to remove the coal, it had to be clea… Vollständig lesen
