My guess is the fuel pressure regulator is leaking into the vacuum line, and the gas is going into the intake. Pull the vacuum line off the FPR, any gas in it?

i pull the one leading from the dashboard area off and theres no gas and the top one on the other side. i did this to replace the vacum hose that holds it together, but that isn't the problem. its only a little gas not a whole lot. its hard to start, it stalls when im shhiftin from r to p or r to d or d r when the engine'* hot. when the engine is cold it runs good. i do have rough idling, and erratic it backfires rarely when its in park, but its not loud.

There should be a line that goes to the FPR. The FPR is on the fuel rail. You need to check that one.

Look behind the throttle body. You'll find it.

The fuel pressure regulator (FPR) is IN the fuel rail directly behind the throttle body. There is a single vacuum line coming into the top of it.

Pull it AFTER DRIVING, and see if there'* fuel in it.
