After key ignition on and clock sweep I'm sometimes getting a single flash from the immobiliser light and then a solid yellow light. I had a list of these somewhere but can't find them. Is this just a simple key misread or something else? Doesn't happen every time.

I'm also sometimes getting the ECU light on after clock sweep and sometimes the above Imob error light too but sometimes just the ECU light and then sometimes its Ok.

Can anyone please help? I seem to have misplaced my Diagnostic leads so I can't see what the error light is being caused by.
