[Peugeot-L] Re: 87 505 N9TE Cold Idle Problem
Hi Peat,
Yes I have some of the manual but its an old one and as an amateur I
find it very difficult to use, compared to a normal Haynes or something.
So how can I test the auxilary air valve? From what you are saying it
sounds like I should block off all flow through and see if the cold
idle problem improves?
Thanks, Dave Towle
