I installed my fuel pressure gauge in the typical spot after my fuel filter. 800RPM 28-29 psi:(, vacuum is 16 steady and timing is about 18. New fuel pump, new fuel filter, and new lines. If I take the vacuum line off the fuel pressure regulator at idle pressure jumps to 36(were I would like to be) I also disconnect the cold start connection(no change). The question is is my fuel pressure regulator bad? all OEM
Thanks.
