My Ride: Silver 325i e46
Engine misfire/lagging

Hey everyone, so I have a 2001 bmw 325i with a bit if a problem. The car wants to run rich and the idle jumps around. I checked for an intake crack but didn't get any reaction from spraying starting fluid around. I had an obd2 test done and the handheld read a bad oxygen sensor; I can't remember which one. When the car warms up, she needs to get that extra winding out of every gear just to get up to speed. I'm afraid I have run out of ideas other than plugs n wires. I figured I'd ask you guys before spending the 120$ at bmw to run a service inspection. Please help!!!!!!!!
