I have just done some welding on my 3.9 discovery. I had the battery off when welding. I have just put the battery back on, started it up and the engine goes straight to 3000 rpm. I had the y section off to do the work and unplugged the lambda sensor on each side and plugged them back in. Can anyone shed any light on this?
