We've had problems off & on for about 5 years with o2 sensors, but now it is getting the worse fuel mileage ever & the engine light keeps coming on. It had done this a while back (but with more sputtering & weak acceleration) & we thought it was the cadilic convertor @ 1st, but it was a coil pack & that of coarse was very expensive. Both times, the rpm's doesn't drop into cruising range & there seems to be strain on the engine. Could this be the problem again? If so, I'm afraid we cannot put any more big $ in it & ay have to sell it & move on. It would be a shame, it's been a very good car.
