My Ride: 2000 323ci
Question WOW!!! I need to know where to start....

Ok guys, this is going to be long but I'm in need of some direction. I have a 2000 323ci with 160k on it. I bought it back in feb and have put only 5,500k on it. It started throwing the SES light again so I got it scanned today at local auto parts store(I need to buy a scanner) and I had what seems to me to be a massive amount of codes. Before I tell you what codes I have I will tell you everything I have completed in the last 5k, :tension pullys,Idler pully,Alt.,PS pump and pulley,spark plugs,both belts,cam sensor:

Parts to put on the I recived yesterday: CVV,valve cover gasket(I have a leak on cylinders 3 and 5 in spark plug tube)

Now with that being said here are the codes I am getting and what their code reader associated them with:

P0173-Fuel trim bank 2
P1477-Leakage diagnostic pump read switch did not open
P1189-Fuel control bank 2 sensor 1
P1250-bmw specific x2
P0170-Fuel Trim bank 1
P1188- Fuel control bank 1 sensor 1

So that is it, I'm just wondering if the cvv,and valve cover leaking into spark plugs could be causing this, or where I should even begin to tackle all of these.

Thanks for the help guys.

What codes were you having before you did the work? Have you picked up additional codes? Go clear the codes, drive around for a bit. Come back tell us which codes are still present. Don't forget, tell us what codes were before and after the work you performed.

Check for vac leaks change fuel filter and fuel pump! Also clean your MAF, this sound like a gas problem for me!
