Take out your plugs, if they are oiled up, the seals on your valves may need replacing as the oil will leak through into your cylinders

this vehicle has coil packs for the ignition correct? have you ran the engine at night with all surrounding lights outs so its really dark. spray a mist of water on the coil packs and spark plug wires to see if you have spark/voltage leaks jumping out from them. sometimes the tiny sparks will be so fine and skinny you can barely see them so it needs to be dark. hope this helps your trouble shooting. a coil pack could have such a fine crack for the voltage to leak from that you cant see it.

Yes my frend open the bonnet and stand infront of the car, on the left hand side between the engine and the boddy there is a black round container with pipes going into it. next to the container there is a vacume switch, 99% of the time this pipes going into the switch is brohen or the pipe is leaking.
