Hi guys,
I just bought a 05 fse450 and noticed that the header is glowing cherry red o after a couple of minutes at idel(because I touched it and then investigated why I had 3rd deg burns,but that's a whole other story). The catch is, I have checked these wires and it looks like the yellow and blue already is disconnected.
Other threads have mentioned getting in there with an injector cleaner but I am a little weary of fuel additives.
Currently have 98 octane fuel in it.
New to the 4t world and the gas gas so any info would be greatly appreciated based in Melbourne.
