2000 discovery is running a little rough sometimes. I pulled the following codes: P061, P0141, P0300, P0304, P0307, & P0160. I know the definition of each code, but what do they all mean together?
Recently replaced crank sensor, but this is a new issue.
All o2 sensors are fairly new as well.
Any help would be greatly appreciated.

How many miles on the engine and when was it last tuned along with new 8 mm silicone wires?Have the rear 02 sensors ever been replaced?

All o2 Sensors were replaced about a year ago front and rear, new wires and plugs within 2 yrs silicone. Engine has 100k on it. Last year I Sea Foamed the intake as well.
