I agree you should get the codes, if you don't want to buy the reader them take the car to Autozone or Advance Auto and they will read them for free (don't accept their diagnosis, get the raw codes and search or post them). If you do want to buy it then print the web page; they told me they have to have that to put in the till.
If the reason your friend is replacing the WP is a blind stab at your issue and not because there are valid symptoms of its impending failure then STOP him. First rule: if it isn't broke, don't fix it. The shotgun approach will only waste money and may create additional problems.
Post the codes and we'll in from there.
Take care and enjoy the ride,
