I Replaced the vac advance on the car today. the old one just crumbled inside and who knows how many years it was in there before i had the car which has been 6. Timming the V12 is the pits i hope to never do it again...

Anyways new VAC, and the TPS fixed I went for a drive and so far Im getting about 19mpg on a straight run I will continue to see what i get but i cant believe it!!!

 

Good work !

Amazing what a functional vacuum advance will do :-). I wonder how many V12 owners have a dead vacuum or mechanical advance and don't even realize it?

Cheers

agree, darn V12s run so smooth,its hard to tell when they dont.

a single miss on v12 hardly noticable, on a 4cyl, whoa, easy to tell single miss, a perspective wait till you have a 1 cyl. engine with a dead miss! hehe.
