Where is that located?

The fuel pressure regulator is located on the driver's side of the engine back towards the firewall. it is a short cylinder shaped piece that has a vaccuum port on the top of it. It should have a vaccuum hose ran to a vaccuum tree or manifold. It should also have 3 hex head bolts holding it onto the fuel rail.

Also, have you fixed your original problem?
I fixed the idle problem...now i need to fix the warm starting problem.

Okay, i think i know where it is...what does it look like?

Nope, never been changed.

Hey CDF302v8, please see my edited post, I misread your post and originally gave you the location for the fuel filter instead of the fuel pressure regulator. Sorry, I must've had a brain fart or something.
