my car sounds awful

[derK]

i installed PTE injectors, AFPR, lexus AFM and since then my car has been sounding pretty bad at idle. It seems to only happen when the car is at full operating temp.

The noise is VERY audible from inside the cabin but outside the car you can't hear it at all. The closest thing i can think of in terms of sounds is a diesal car. It sounds close to a diesal car, obviously not as extreme but very similar. If i bring up the revs the sounds disappears or it could perhaps just be drown out from the exhaust noise.

Any ideas?? it can't be my injectors making that much noise.

I know my car sounded like a diesel when I had a spark plug wire crossed. Dont know if that's you problem, but you never know.

i put my fuel pressure to stock pressure. I thought at first it could've been the injectors, but no i don't think it is. The "knock" is just too loud.

if the ideal is very low you will hear a nock

should be like 650 to 750 between that range

yep idle is within specs....

thing that gets to me is that the noise isn't audible at COLD operating temps. However when the engine is warm and all the materials expand that is when the "tick" comes out,
