What tests would you recommend to narrow it down? On a scale of zero to "Take it to the shop", how hard would it be to replace the leaky fuel injector if that's the issue?
I'd drive it till fully warmed up(when issue starts) and hook up a fuel pressure test gauge and then start engine(or try) and read the PSI.Shut off if it started and watch pressure gauge,it should not drop more then 20psi in 30mins.If it drops much,much faster then you need a more advance pressure test kit to isolate the injectors and pump to see which one is bleeding down since it's a "returnless" system.
