Hi there, I am Cam. Can I get your first name please? I am sorry to hear about this issue, your thoughts on where to start are good. Lets look a bit deeper. With this noise, does it happen all the time, only when hot? What is the history to this issue? Is the check engine light on?
Ok, how did it process? Did it start all at once?
Ok the noise was only with the torque converter connected? Does it go away or change with engine speed or engine load aside from getting faster??
That actually does not concern me. Provides there are no cracks around the bolts that hold the flex plate to the crankshaft. Does it look like it was hitting anything?
Does it make the noise when you hit highway speed and the torque converter is locked up?
Strange. MY first thought is that there is a fault in the torque converter, but then to have it at idle is not typical. IF it was me, I would use my scanner to lock up the torque converter at idle and see what the noise does.AS for history, did this start all at once or just start to get worse?
Ok, How many miles do you have on it?
only 10000 miles?
ok, I may have something. I am starting to run into some that have carbon build up causing an odd knocking type noise. Lets start very simple and do a combustion chamber cleaning to remove some of the carbon build up.
It should not hurt it at all. You should be able to run regular with no issues. Spark plugs will be due by now as well. Knowing that I would also consider new plugs. Don't gap them, just get and replace. If they are out, take them back for warranty as they come gapped properly. Don't get really expensive ones, AC Delco are just fine for yours.
