Just a quick post to tell you the Defender is cured, "Redex DIesel System Cleaner" was put in the tank this morning and after 10 min the engine was getting better. I took it for a 15 mile run and I have never felt it running better. This was a chance decision to try until my IP removal tool arrived, and i was going to get the IP reconditioned. Best spent £7.50.
Thanks to everybody who took the time and tried to help me....much appreciated.
