my car is running like poopy and sometimes throws a code 43(fuel supply) and the car dies at stop lights sometimes when i throw it in neutral. and i was wondering if it could be from my fpr being set to high. the fuel psi gauge reads 50-52 with the vacum off and car idling...

 

should be between 35 and 40 psi

 

35-40 psi idling with vacuum off? or with vaccum on?

 

with the vaccum hose connected.
