U1612 Possible Fix :
If the culprit is a poor fuel pressure regulator, then I suggest looking around for a replacement part and taking your car to your local mechanic for installation. If you're a skilled mechanic, then you should be able to install a new fuel pressure regulator easily. But if you're just starting out, it's always best to have the professionals take care of this job. Believe me, the fuel pressure regulator is not an easy part to install.
