I have a 1999 chevy z-71 with the 5.3 motor. the problem is i am having
a misfire on cylinder #5. i went to have it check out and the mechanic
told me it was the fuel pressure regulator. i replaced it and the motor
is still acting the same. any ideas on what else it would be would be
greatly appreciated.

Step 1. Find a new mechanic.
