Hi everyone 

I was wondering if I could get some advice on what might be the best solution for a check engine light coming on briefly at high rpm before the gear changes on my auto legacy gtb bh5. I put the scan tool on it and it comes up as cam a sensor.

Another problem, perhaps unrelated is that it only just passed emissions as it was high on CO. 

Any help would be appreciated.

Thanks 

I would get it to a specialist to get it checked out, could well be duff cam sensor, which could be bad if left.

Thanks mate 

I will. I think it's a sign not to overload it but treat it with care.

yeah, could be its pick up knock at high revs, tbh sounds like it my be worth a run on a dyno to see whats going on.
