Hi
Our LS seems to be pretty reliable, due a service about now. However the other week we had just under half a tank of fuel and it appeared like it wasn't running as smooth so we filled her up, incase it was a shortage of petrol somehow. It's happened since. Starting, running, acceleration is fine. It is difficult to describe, just appears to be intermittent thing either hot or cold. Normally the needle stays at about 600rpm but it drops down or goes higher (without air con on) Its going in next week for the :shutit: service but could it be a spark plug or something like that? It was last serviced June 02 and only done about 8000 miles since. Thanks :D
