i got one from a j/y this weekend and when i installed it the car will not idle. i hooked it up two different ways and still the same thing. i havent tried to adjust it yet. anybody know the deal with these setups? need help thanks steve
Sounds like you have a vacume leak somewhere.
Are you dumping it between the VAM and the turbo inlet? If dumping it before the VAM, it amounts to a huge vac leak.
it was just to atmosphere. im gonna tighten down the adjustment screw and see if that helps. i have 19" of vacuum at idle. as soon as i hooked it up it would not idle. i guess ill play with it for a while and see if it was worth the $10 i gave for it. i read earlier that they are set really light and open somewhere around 5" of vacuum on the volvos. so it at least needs adjusted right.
