Hey everyone I have a 99 Mustang GT and I need some advice... I recently was having a sluggish feeling when I give it a little gas. So I went and got a diagnostic check and it read my 5th sparkplug was miss-firing and that my bank 2 censor was malfunctioning. I know I’m in need of a tune up but what about the cat... do I need to replace both or can I just replace the faulty one?

Don't touch the o2 sensors, give the car a tune up and clear the codes. A misfire will trigger other codes such as O2's
