complete exhaust system, needed it anyway, 200k miles still had original exhaust on a 2001 car- $500, installed it myself
any bad sensors, coil, etc. returned for full refund

it needed it all, and then some- for roughly $1500 the car is reliable again
that'* not a lot considering what was done !
Monro wanted $750 just for the exhaust parts and installation.
I did it all myself except for the final scan and crank relearn part.

I know there'* a vacuum hose that goes inside the cabin and it runs inside one of the wiring looms. I had a problem where it transitions from rubber vacuum hose to plastic pipe, it'* hard to see because it'* in the loom. If memory serves its the smaller hose that comes off the plastic fitting in the back of the upper intake.
