I have a 2007 Accord v6, about 152,000 KM, runs smooth other than some times I get a vibration and a BRRRRRRR sound only when stopped at a stoplight in gear D

It only happens some times. It never happens when moving. The vibration also stops momentarily when I turn the steering wheel left or right a little bit. It stops when I throttle and go to 900-1000 RPM, idle is about 650-700.

Sometimes when I go to N or P the vibration stops. It's most pronounced at D, but some times there is no vibration at all even on D.

Whole lot of things it could be. Loose converter heat shields, exhaust or transmission mount bolts, maybe low P/S fluid level since turning the wheel helps.

It's likely to be the transmission mount bolts. It was recently changed but I don't think the guys at the shop installed it right, or didn't torque it to spec.

I checked the P/S fluid, and it actually over-filled a little. All other fluids OK

Check your heat shields

I drained some of my overfilled P/S fluid to the lower level mark, if it helped the difference is probably so small that I can't really tell.

Now that the weather is getting warm here I turned the AC on for the first time this season and it actually made the idle rumble noticeably stronger. Idle is around 600-650. There is no tinny sound from the heat shields though.

Remember when I said turning the steering wheel reduces the rumble? Well sometimes it makes it stronger, depending on position. I also feel it the rumble gets stronger on slopes. Especially side to side slopes

Upon further observation, I noticed that when I turn the steering wheel when stopped and idling, I get a power steering whine noise (not loud)
