well i have a bad vacuum leak or leaks coming from under the UIM. i hear the hissing from afar and when a buddy decided to do check using carb cleaner . the car started stumbling.

now the main problem is how can i create pressure to source out the leaks?

on my other cars i would just pressurize the system from the turbo with an aircompressor and whatever i heard leaking i would fix...

i dont know how to do this with a twin setup.

any pointers on what can be done.. i plan on taking off the UIM on wednesday and start replacing my vac lines under there.


FYI... im non sequential
