My vehicle has two main problems: exhaust fume and spark plugs full of coal. The tires have been repaired and all the sensors changed. Yesterday, the coil was failing and only 2 cylinders were working, so this failure was corrected. Even more, I've added a smoke remover product and cleaned the spark plugs, which were certainly well-worn. Its inmediate response was a good one but, after a while, it started failing again, this time there was a power loss when changing to Drive. I bought new spark plugs and, until now, it has responded properly; I'll check tomorrow if this persists. I would like to know if anyone knows why the spark plugs are being filled with coil.
The timing belt of my vehicle damaged and affected the valve, the valves have been replaced and upper component of the engine was cleaned, the upper gasket was also replaced but i noticed that since the repair, my car do smoke for few minutes after starting it and stops. While driving the car doesn't smoke, it only smokes when i start it in the morning for few minutes
