Did it have a p0089 code?

So was the car going into limp mode? I have had the check engine light come on multiple time and it goes into limp mode and scanner says fuel pressure regulator performance is the code i keep getting. It also shows long term fuel trims are adding like 16%. Is this why you changed the regulator? Other then no power what else was going on? Im working on the same car.
