Hello Doug,
first came across this with a Holden Jackaroo (2000 model) that had the 3 litre Isuzu Diesel in it, never did find and answer ( S9+20 on 7 MHz ) so the way to tell if it is indeed the injectors is to find a slope and then let it cruise down the slope with your foot OFF the acelerator, then the injectors are not being pulsed as fuel will be off (assuming it is a manual transmission car) then the receiver will magicially go very quiet compared to before. Not sure how to do that if its an auto, maybe lock it into a low gear on the shifter?
Once I proved it was my injectors being pulsed, it all got too hard as we were about to take a 3 month trip and I did not want to compromise our reliability by fiddling in the engine bay . . . so it was full throttle on TX and glide along for short RX periods when the need occured, otherwise its was only use the 706 Mk2G when stopped.
I now have a 2016 Holden Colorado spacecab ute with the G.M Duramax 2.8 and it is a whole lot better than what you describe. I did hear of a kit that the holden dealer could fit to improve 'rural AM reception' so I might ask about that for mine, you may want to ask Isuzu if they have some thing similar? I too have other squeaks and squarks from other modules that give me blips across VHF SSB, not looked at them yet.
