2001 ford f150 4x4 5.4 problems

my truck is shaking and idling very rough,i have replaced the erg valve, a few coil packs,cleaned injectors,new pvc valve, and new plugs after all that it ran fine for a few hours then started all over again. What ever is causing it makes a smell of raw gas coming from driver side and has blown my converter out plzz help ???

Take a flashlight and look at the fuel rail are any leaks observed. Look for a vacuum line going to a pressure regulator on the rail. Pull the vacuum line if any gas is observed replace the regulator. I looked at a couple of regulators.
Vin L was $76.00 and the other one was $1276.00 hopefully you have the cheap one. This is a picture of a fuel pressure tester.

Look for any gas leakage along any fuel lines put it on jack stands and look carefully. You may need to check the vacuum canister.
