well replaced CTS, to no avail.
MAP and TPS are all thats left, oh there's a crack in the knock sensor,
(happened after this trouble started) but I dont know if that would affect mileage or not. I thought the knock sens, was there to help in the event that you get gas from Mexico or whatever

I thinks its just something you have to live with...If not, ****, you must tell me your secret!
My Renix gets around the same MPG's.....Yes I feel it bombing the hell out of my pocket as well.

Oh well tho, I still love my Jeep
