Engine/Transmission Roughness
I have a 06 TL Auto with 30,000km. I find that when idling and when the engine is running at about 1500RPM there's a bit of a roughness. It's most pronounced when cruising in 5th gear at 1500RPM. I'm using Amsoil signature 5W20, have changed the transmission oil with DW-1 several times and even changed the spark plugs. It's also pretty rough when the engine is very cold and just started. Is this normal?

That's what I was thinking. Are they adjustable or need to be replaced? I bought last year with only 10,000km. Was from an old man that never really drove it and was never winter driven either. It still smells new inside.
