2005 WK grand, USA<> right in USA>? gas engine sure.
all modern jeeps can do that. 1988 to now.. (exceptions dont apply here)
all vacuum leaks do that ,ever time..
and by any MEANS>
that means if the the ISC sticks open as is ALL SO COMMON
that is a vacuum leak. it sucks air the MAP sees that
an mixed fuel like magic, all on purpose and normal. for a
all map engines made (called speed density systems)
cracked vacuum hose (all of them or suspect)
all THINGS , on end of all those house must not leak air.
even the brake booster. must not leak,. see?
it can be simple as hose or , the end of hose device bad.
or ISC stuck.
ever lean the ISC?
idles speed controller ? gumming inside they all get.
from "EGR+PCV gas clouds of *****" i all them.
those two nasty forces make gunk and cause things to stick
its SMOG fumes there.
why do you need a stealership, ever heard of and ASE shop
google ASD shops by ZIP..
tell him you have a vacuum leak, he will find it
good shops have smoke machine to find them, takes skills to use.
one trick (have 10) is to pinch vacuum hoses or block them
RACE NOW? no , bingo.
finding some leaks are long hard hard work.
nature hates a vacuum so,, guess what in the end it finds a leak
and exploits it. (on earth not on the moon, max vacuum there)
