That is the only thing i can figure. I've even tried downshifting to 3rd when going 50 to try to find that sweet spot at a "normal" speed but no dice.
I'm at a loss as to why the mpg have plummeted lately. I repaired a vaccuum leak which made the car run much smoother (it wouldn't idle, it would lope) but it seems that now my o2 sensors have faulted because the mpg dropped like a rock afterwards.
