Hi, sisters car broke down months ago - she left in on the drive. Today I had a look at it, got it running by holding key over, warmed it up abit ticking over about 4/500 revs - when I tried to throttle it, there is a timing knock and the engine cuts out. (R- Reg 1997 1200cc) anyone got an idea of where to look - she supposely had it on a diagnostic machine and can't remeber what the guy said - though he did mention the key was faulty which I can't get my head round SB
