Hi I am having an engine misfire for the past 3 months. I have got the spark plugs coils and manifold gasket replaced. But the problem is still there. I have tried 3 different types of coils but each time I replace them the car seems to work fine for about 2 weeks but after that all of sudden while driving the car will have serious misfires and traction control sensor errors start coming up. It’s weird I am not sure what to get fixed next. Please help I can’t afford to stay of the road for too long and can’t afford a new car.
