idle issue

MA70-3.0GT · 11-09-2009, 12:10 PM

Right I've just got back from a (very cold) session of vacuum pipe route/integrity-checking & I think everything's where it should be now. One thing I did notice was that the pipe to the fuel pressure regulator was split. Lucky it was long enough to cut the knackered portion off.

Now I'm assuming (correct me if I'm wrong) that as well as increasing pressure on boost it would also be affected by vacuum at idle or lack thereof, and could be one cause of a rich condition off boost before leaning out on boost... Anyhow, I'm just waiting on batteries to charge before I go back & spin it over again and find out.

I could do with finding a new accordian pipe too as the original's got some cracks which I've sealed with tape for the moment, the damn thing's like glass!!!
