Hey guys, just asking for some recommendations for places to take the legnum in for a service. only got it a few months ago and the oil and ATF fuild looks quite healthy, previous owner said it was regularly serviced, but who knows no records....
would like to take it in for a "full service" anyway
and also get them to investigate a rough idle problem /Grrr .
i have done some investigation myself, removed BOV, checking visible hoses etc for leaks,
im pretty sure its a vaccuum leak of some sort as you can hear a hissing from the area above the belts on the left of engine bay (see pic, sounds like about 15cm below circled area but sound does weird things and could be anywhere...), but its not coming from the turbo pipes. Also i have noticed the boost gauge vacuum is lower(closer to 0/boost) than it used to be at idle. used to sit about 500mm/hg now its about 300mm/hg which helps suggest some kinda leak? maybe?
havn't checked some of the other rough idle solutions mentioned on here yet like the stepper motor, mainly coz im pretty sure its a vacuum leak due to the hiss that im sure wasn't there before the issues.
