So i've been watching youtube and looking on other forums for the location of my fuel pressure regulator and they all said that it was under my intake so i took my intake off and it wasnt there. after i put it all back together and started it up it was idiling between 1500 and 2000. it jerks hard when i put it in gear. can anyone help me with the location of my fuel pressure regulator so i can replace that and my issue of it running lean?

 

I'd check for vacuum leaks first.
