The vehicle listed above has V6.
Recently it has been making a muffled popping sound intermittently from the air filter box. It runs fine. After having codes checked, it came back with the following; P0193 - P0420 - P0430 - P0506.

The P0193 code is the one that can cause all of these problems, fuel rail sensor. Here is the location and how to change it out in the diagrams below with a video of the job being done on a similar car:

Ken, you are a genius! I never suspected that all these codes could be caused by a single malfunctioning part. I replaced the fuel rail pressure sensor as you said and the codes have cleared. The vehicle is running normally again.
Many thanks to you all!
