When I’m driving my brakes and power steering go like concrete ? Any ideas?
 

Hi, thank you for reading. It’s an auto x type jag 2004 4WD with an 02 sensor gone but mechanic didn’t know which one so light still on? Mostly, when I start I have to with engine in, go into drive, then there is no brakes or steering but it moves so have to bang back into Park Then back into drive again to go anywhere. Today I was already driving down the road bout a mile when it happened again when I went to stop! Exceptional Grindy metal noise from gearbox when shifted into park, now scared of it lol any idea,s for cheap fix?

As for your O2 sensor, if your "mechanic" didn't know which of the 4, get another mechanic. The code they throw tells you which it is.
