Sorry for the impending weather, but I actually worked on the Buick this week. I installed a new Pypes exhaust, did the Kirban rear seat braces, and also removed the oil cooler to fix a leak.

That said, with the new Exhaust, it almost seems as if the car is running richer. WOT seems to be reading in the 780s and idling is in the mid to high 800's. I dont remember it being like that before, and I believe I even set the translator one click back to try to lean up the idle exhaust (eyes burning). You would think a better flowing exhaust (aka one without 25 lbs of dirt and rust inside) would actually lean it out rather than richen it up. Any ideas?

It's expected the car is experiencing what is called New Parts Shock leading cause of old motors being able to breath again!!! :D or you have an exhaust leak somewhere.
