Finally got my car back from the dealer. Needed a new computer, and everything is happy now.
The car still smells rich, though... There's not any codes SAYING its rich, but it smells rich. Gas mileage is also poor. (Getting about 14 city... Figured i'd at least get 16 or 17) Are there any common issues with the 3.6 that could cause this? I read that intake manifold bolts like to work themselves lose on the N* (as well as head bolts), but does this apply to the 3.6 as well?
The car has power, and it drives pretty well. It just smells rich at idle, and seems to drink gas while idling... That, or i have a fuel leak, and gas wasn't siphoned out of the tank by the sketchy dealer it was at for a week before it got moved to the Cadillac dealer. (I gave it to them on half a tank... got it back with .5 gallons left)
I read that the gas tank on these cars is a horse shoe shape over the drive shaft. Would this cause what i'm seeing? If i park on hills, i've seen the gauge go from saying 7/8th of a tank to under half in less than an hour. I can't really find any rhyme or reason, though.
