Vacuum leak?
I found that my car was running rich with the new fuel pump so I attached a fuel pressure guage to crank the AFPR down a few psi.
Pulling one of the plugs on the intake to allow a vacuum leak resulted in no spike in FP. Isn't it supposed to jump as much as 5 psi under this condition?
I did a cursory search for a second leak and found nothing, and a vacuum gauge has it at about 13-14 mm/hg. That seems about right with my cam (see below).
Thoughts?
