So recently my cars not acting the same, it doesnt feel the same; referring to the way it drives, not sure if its limp mode or not. When turning the car on at cold starts it takes the usual 1-3 min to idle down and right before it idles down a big rattle sound comes form the exhaust "im assuming" and recently at red lights the car has rough idles, and vibrates very lightly.... After all this being said a service engine light came on and off for the past 3 days, i got to scan the code and only got to pull one code which was a o2 sensor failure -_____- which i find hard to believe because the car only has 24,000 miles on it. What do you guys think, would really like to hear your opinions on this. Im gonna take it in soon, but want some background knowledge before i take it in to the stealership.

Thanks

A faulty O2 sensor can cause exactly what you're describing. (Happened to me on one of my vehicles). Even though it only has 24k it's not impossible. Like the M3 that needed a new engine at 1,800 miles when I was at the shop the other day. $24,000!

Probably anywhere between $100-250. Have you done your HPFP recall? Could be some bad injectors too.
