Fuel entering the intake, this can be from fuel injector to fuel pressure regulator that leaks through its diaghram,

Scan for codes and check fuelpressure first. This particular engine has a tendency for the throttle plate ot get sticky and casue problems clean it on both sides with choke cleaner as well as iac hole.
