I have a Hyundai Tucson , 2008 model.
About 20 months ago while my wife was driving the car, some smoke come out and she stopped the car and they tow it. (She doesn't remember white or black smoke)
After that in about 6 months car started to studder while I am driving. It was skipping a beat. I take the car to mechanic and change the spark plugs. One of the plugs was really wear out.
Next time, probably in 4 months after that same problem. This time I change plugs plus the ignition coil. Problem solved and come back after 3 months.
I have been changing plugs regularly so that I can use the car. I suspect at some point of time car overheated and engine block got damaged and there is water in the engine as a result and that is the root cause of all studder problems. Do you guys agree?
I will throw the car away in another 20 months. (Where I live cars are expensive and you get to use them only for 10 years). Shall I get it properly fixed or just keep changing the spark plugs and use it until the license expires?
