How to fix a misfire in cylinder 2?
What repairs can fix the P0302 code?
- Replacing spark plugs that are defective or damaged.

Vacuum leaks, especially those that are confined to one cylinder, will cause the engine to idle unevenly and possibly misfire. This is because the vacuum leak allows additional air to reach the affected cylinder, diluting its air/fuel mixture.
How do you test an ignition coil?
Here’s How To Diagnose and Test An Ignition Coil
