Just a quick note to say Thank You to all the knowledgeable gurus on this site. After a well known L/R Wksp insisted that my MAF was responsible, I took notice of the info I was given on this site and changed my ECU Temp Sender Switch. My Disco V8 is now thanking me with a more complete and leaner burn. Havent got any fuel figures yet but the exhaust is definately showing a better burn ratio, not so rich and sooty black. So, once again, this site and its members has proven itself invaluable in the knowledge and advice given. Many thanks. Bob
