2002 ford ranger 4.0 sohc
P0172 & p0175 codes rich bank 1 & 2

Truck runs seems like gas is going quicker on the gauge no smoke.

Trying to get some help if possible with these codes hopefully the freeze frame data helps waiting on a live data scanner. In the mail.

In the photos show the freeze data and I did a fuel pressure test results are on paper in the photo maybe someone can point me in the right direction for what parts I should be looking at any advice helps thanks in advance.

Key on engine off 60psi drops immediate about 10psi in a min
Key on engine on 83psi

engine on damper vaccum off stays 83psi
damper not leaking gas has vaccum suction at line

engine on damper vaccum line on stays 83psi

engine on reving 2k 83psi goes down as reving 5-10psi

TroubleCodes p0172+p0175 are typical when there's a vacuum leak;
check those 5/8"ID rubber elbows in the PCV Hoses (notorious for cracking+leaking)
going from the rightside of the IntakeManifold to the PCVValve on the rear of the LeftValveCover
& from the AirFilter~ThrottleBody AccordianTube to the RightValveCover.
