Here is a good video on MOSFETs, and what they do. If the MOSFET controlling cylinder 2 is fried, you can have that individual MOSFET replaced (requires removing old MOSFET, and soldering a replacement on the circuit board in the ECU). Otherwise, you will have to replace the whole ECU, and that can get expensive.

Thanks for the suggestion. I will check regarding the coding. But with mosfet if there is a issue, i will see problem with misfire all time or after running for few kms and that alao just while starting the car. Any thoughts on that?
