Renault swb Trafic van 1.9 (keeps going into limp mode up hills)

Description:

Hi i would like to swap my trafic van for something similar. this could be an easy fix but I just haven't got the time to see what the problem actually is .this van is fully ply lined in the back and is spotless in the front.Please let me know what you have.thanks I will update more pics when I can but overall is a very tidy van for its age.. it is in daily use and has done 165000.ideally would like to swap for a transit van but it must be in good condition. I am a genuine guy who would also like to deal with the same back.
