Hi,

This has just came on recently in my focus. I had it turned off by my mechanic but unfortunately it has came straight back on.

I have read various threads regarding the DSI clip and IMRC.

I stripped the bay and checked the DSI clip which appears to be working fine, it moves when started and moves again when revved beyond 5500rpm so that can't be the problem. This would also suggest that the IMRC valve is also working and not stuck open as suggested in other posts.

Could anyone enlighten me as what else could possibly be wrong?!

Thanks
