Replaced sensor, air boots

My car is 325i, 2004. The car didn't pass the emission test. The dealer recommended changing the cyclone separator and the disa valve, both got changed but didn't solve the problem. The problem is when l try to accelerate the car shots down and bunch of lights comes on on the instrument panel including the EML light. I have to shut the engine completely off then restart ithe again. Nobody seems to know what the problem is. Can you help me please. Thank you very much.
Two codes. P0171. And P16A7

When driving the cars power fluctuates
And you can see it doing it if you look at the energy control meter
Its needle on that meter goes side to side rapidly slightly

Sputters out

The battery is strong,the car was working fine,drove it and parked in drive way and now it won't start,key doesn't close or open doors,ones you turn on the switch you can hear the gas pump working,the lights are ok,but it wont crank up,it just won't start

I have a 2003 325i and typically in the mornings it has a hard time shifting from reverse to drive. It takes roughly a few seconds to engage into the drive gear. Once it has engaged into the drive gear there seems to be no issue. I just had the transmissions filter, transmissions pan gasket and transmission. flush done with still no change. Actually, it does seems to engage into drive from reverse a tiny bit faster now. Any ideas????? or similar problems???

How would I no if I need a cat r a O2 sensor o 2 sensor

Not sure if we need a total brake job or just need brake pads. Would like the worst case scenario please.

When I turn my radio up it blows fuses and my dash lights quit working along with brake lights and/or the whole right side lights

when I bought it I was told it idles rough when it got hot and it was because of the intake hose is this correct. When its not hot it does not make the knocking sound at all.

both oxygen sensors bank 1&2 at 35,000 miles, the service engine light returned again,the car runs fine, but I need to have the car smogged, What should I do next. By the way the car now has 109,000 miles. Appreciate any help.
