I noticed after removing the battery briefly and putting it back in, every time I would have stalling issues. This happened on several occasions and then eventually smoothed out so I didn’t think anything about it. Recently the engine light started flashing so I pulled over and scanned it. The scan turned up a cylinder 5 severe misfire. Replaced addition, coils and spark plugs, but noticed that it smells heavily of gasoline when running and they notice an excessive amount of gasoline in cylinder number five when I replaced the intake manifold after changing, spark plugs and coils. I am kind of stumped as to what this could be. Any pointers or advice would be helpful
