momentary engine vibration

[Pumaro]

If I am waiting at a stop light every minute or so the engine resonates/vibrates. has anyone else experienced this?

[Towncivilian]

It could simply be a rough idle, in which some fuel system cleaner might help. Perhaps try running some fuel system cleaner like Redline SI-1, Chevron Techron, or Gumout with Regane. All three of these contain a significant amount of polyether amines, which is a detergent co-developed by Chevron and BMW to effectively clean fuel deposits without leaving behind deposits of its own as solvents and other cleaners do. Redline SI-1 contains the most PEA out of the three.

It could also be a motor mount or transmission mount, but since your vehicle is brand new I highly doubt that. Are you running at least 91 octane fuel?

[Pumaro]

It didnt say 91 octane fuel anywhere, so I am using 87 octane. Do the 2012 Armadas need 91 octane

Armada is designed to run on 87, I have never had any issues doing so. Keep an eye on it, if that continues to be an issues just stop by the dealer. Make sure you can mimic the problem though. They cannot help if they don't hear/see the same thing.

yeah armadas are set up for 87 minimum. however, if you have been using cheap gas this can also cause some deposit build up.

nissan does not recommend using additives as per the owners manual. that said, i used to use redline. lucas oil was also a good additive...

Did that take care of the issue?
