Hello!

my LR 90 has just, over the course of five miles, lost all power. Injectorsmstill working (AA man checked) but couldn’t work out what was causing it. I can start her up, rev, but not move the car. Black smoke coming out and the whole engine shakes - originally thought it was a misfire but it’s worse than that. Last serviced in the summer…

any thoughts on what it might be?

thanks!
