O2 Sensor problems of the 2007 Subaru Tribeca

While driving this car it constantly loses acceleration. It will have no power then lurch forward and rev. It idles, lurches, and then has no acceleration. I have also replaced the sway bar bearings twice in this car as well as 2 oxygen sensors, and catalytic converter. The deal still cant fix the problem even with the service codes. This car is a danger and a safety issue.
