Engine Warning Light

[plee]

Hi,

I have a Manual LS Focus CL and the Engine Warning Light has come on. I have done about 22,000kms and the car still seems to be running smoothly. I have booked the car in for somebody to have a look at it, but was just wondering whether anybody on here has had anything similar happen with their car. I am using 95 Unleaded primarily with a bit of 98, have had the car starting issue a few times, but nothing recently.

Any recommendations/advice would be appreciated.

Cheers
