update people,

Ran the car for a while, temp went upto 90 deg and stayed there.

Pluged the scanner in and still got the same fault

Every so ofter the lambda sensor code woud come up saying - low end
I understand this is to do with the misture running rich ? am i right ?

On those crossflow 1.6 8v engine the coil pack and or the leads go wrong most times, also check that the two middle(2 & 3) plugs have been replaced as those two are a really pain to get to and sometimes don't get replaced.

I replaced the plugs and leads about 4 months ago, so that should rule them out any other ideas ?

Does yours have a single coil pack? as some early ones had a distributor. Check for a misfire by removing one lead then starting the engine and see if its the same or worse, then refit that lead and move on to the next one.

its a single coil pack, ive done that already. and nothin changes really, its running fine no misfires etc. just the above what i mentioned.
Like i said its saying - camshaft sensor - no signal.
