Good to hear!

The FPR uses vacuum to change the fuel pressure. Lack of vacuum tells the FPR to increase the fuel pressure by at least 4 psi, enough to flood the cylinders with gasoline at idle.

Start checking the vacuum elbows the next time you have the hood up. Replace those that are very soft or cracked.
