Hello,
My sisters Taurus has been throwing fits lately.
Some days it surges while driving. This morning it just refused to restart without some help from the pedal.
I recently pulled off a P0430, Catalyst efficiency below threshhold, bank 2.
This sounds like either a cat or an 02 sensor. What I've read up on so far, it sounds like the cat.
I've heard in the past, that "cat's don't just die. They're killed."
If I swap out the cat, would it also be wise to go for the 02 sensors? I'm worried the one(s) on the manifolds are telling lies, causing the poor running/starting.
So... If so - All of them? How much do they run?
Thanks,
-marc
