Question

I have corrola 2010 the code shows Cylinder 2 misfire. I changed Coil, Spark plugs, and Injector. All of them are factory. But unfortunately after 2 and 3 days the Engine indicator light comes on and the same code shows us Cylinder 2 misfie.
What you think is it? Something's else or what !

HI there

If you can feel the misfire at idle, it could be a vacuum leak at the intake manifold gasket on that cylinder. With the car idling try spraying some carb cleaner along the intake and see if the misfire smooths out or the idle speed increases. If it does, then you have a vacuum leak that will need to be repaired.
