Each personality type can potentially irritate other people in their own particular way.
The potential ways in which an ENFP can irritate others include losing sight of the main purpose of the discussion and going off at tangents. You may initiate too many projects and are therefore not able to deliver on all of them. Some people may think you talk too much, introduce too much change, and don't leave well-established, workable routines alone. They may even suggest you exaggerate or make errors of fact, or at least want to pursue ideas without fully thinking through the consequences in, say, cost terms.
You can overcome personality type differences by learning about your similarities and differences with other people. This leads to greater understanding, appreciation, and respect. Also, if you learn to adapt your style this will make you more influential and respected.
There is a comprehensive guide on how to do this in the book Influencing People Using Myers Briggs. This is available as an option when you complete the personality test.
