Hello, Before you start repacing parts. Start with some good carb spray. Make sure the cooling fan is not on and the car warmed up. Next add the extension straw to the car cleaner and spray carb cleaner around your number two intake manifold gasket. Focus the spray as close to the gasket as possible. If your sudden miss goes away I would suspect the intake manifold gasket. If it doesn't, then go and check the spark plug, swap #5 to #2 spot. If no difference, then swap the coil 5 with 2. If the miss jumps to #5 then its the coil. If it stays the same then, as the car is running, lift up on the number two coil, do you here a sharp tap, tap, tap sound? Then the coil is working. It could be the power stage, swap them from front to back. If all this fails to take care of the miss, then go to the fuel injection, but not untill. It will save headaches
