Engine Performance problem
1997 Ford Aerostar 6 cyl All Wheel Drive Automatic 115000 miles
The problem started a week ago, the van was running fine, then all of a sudden it started to idle rough, when in gear it is much worse, actually more like a really bad surging plus rough idle acts like it might even stall, when accelerating its terrible! Feels like the thing is running on 3 of the six cylinders, the check engine light came on a few days later, had the code read, and states bad Oxygen Sensors, my question is, could these be causing all of these symptoms, or am I looking at an even larger problem, I don't want to change the Sensors if they won't solve the problem.
