Re: vacum leak

first dead giveaway...at idle your boost gauge doesn't show around 18-20in-hg vacuum

i had my wastegate signal line unplugged and only showed 10 at idle.

next step, look for loose hoses and holes in hoses.

Re: vacum leak

run some soapy water over the vac lines and look for bubbles?

Re: vacum leak

what about a light spray of ether/starting fluid on each line to see if the idle surges .

Re: vacum leak

I'm n/a right now, but hooked up my gauge any way to get it done and out of the way. Anyway, I vaccum only at 15-16 idle and cruising like 16-18. Is that still okay?
