2003 TD5 In a Defender 110 - Limp Home

Go up a hill and add throttle ( almost full throttle ) and it will negate the throttle and go into limp home mode - recycle the key and everything is back to normal. So up a grade add throttle and engine light and no throttle - happens in low box or high box only thing constant is UP HILL and THROTTLE other than that performs very well !
