The engine mounts would not cause this problem. But is the check engine light back on now?
Let me look for technical bulletins from Nissan. Be right back.
I did not see anything other than what you have none. I will opt out and see if another expert may be able to help.
Hi my name is ***** ***** motor mounts are very low on the list of possible problems. being that the engine has been under heavy misfiring for quite some time, with a smooth operating period in between, misfires will absolutely destroy catalytic converters. my advice would be to have the cats checked by doing a backpressure test just to eliminate that possibility
being that it is a well documented issue, not by dealers or mechanics, there would be no harm in giving it a try. as far as the codes, they can be 0420, 0430, and a few more...but definitely have them checked anyway
