I am hearing a cyclical, vibration type sound while idling. I just started noticing it right after my oil change yesterday, thuoght it might be a diesel mercedes at light behind me. Nope, it is my 2004 T4R. I switched to a synthetic oil. Jiffy Lube checked it out and found nothing wrong as far as oil change and that goes. Its almost like a purring, vibration, not sure where its coming from, any ideas? Maybe Catalytic converter, I really don't know.
Odd sound while idling?

hmmmm... The idle may be lower than normal, and something is loose in the undercarriage. I don't think its the lifter.
but to be honest I don't trust Jiffy Lube tho.
