Default Re: Need help with vibration in new motor!! (5th gear shimmies) PLEASE HELP!!

Okay I got codes 91- O2 sensor low voltage/system leanor voltage out of range so I need new O2's.
But I also got code 95- Fuel pump secondary circuit fault.
What is this? Either of these could be my problem because it runs fine every day until i shut it off so I guess it's running rich as per called for by cpu when I've just started it for the day.
but what is this code 95 and how do I fix it??
HELP
THANKS
WES
