I have put in a 14 psi spring in my fuel pressure regulator. I have also added a fuel pressure guage on the return line. My truck runs ok when it is cold, but when it heats up to operating temperature, it starts to idle a little rough. I was wondering if I should just put the 12 psi spring back in?
Any help would be appreciated.
I have already replaced the wires, rotor cap, iac, etc.
