SOURCE: Help 10 codes on 323i!

These codes will have to be cleared and the car driven through a drive cycle, maybe a couple of times, is the check engine light off? Also you should check your MAF sensor it may need to be cleaned or replaced and makes sure there are no holes in your intake tubing. Hope this helps, let me know.

SOURCE: 1998 mazda mpv code p0170 erase code car runs fine

This code indicates a fuel ratio problem. I would start by inspecting all the vacuum lines, including the pcv hose and power brake hose. Carefully inspect the air intake hose. This is the large hose between the throttle body and the airflow meter. If this hose is cracked or loose the computer will not sense how much air is being drawn into the engine and it will be hard to start.

SOURCE: Just got there codes for my 2000

P0304 = #4 cylinder misfires
P0170 = Fuel Trim, Bank-1
P0173 = Fuel Trim, Bank-2
P1250 = this is invalid code for BMW
P1188 = Fuel control, bank-1, sensor-1 (pre-cat sensor)
P1189 = Fuel control, bank-2, sensor-1 (pre-cat sensor)
Vacuum leaks and/or sensor defective for the issues of the codes.
This error codes really need parts to replace. But you have to replace the thermostat first. Then clear the codes and see if any reappears,then replace defective part/s

This realy sounds like a fuel problem filter or the pump you are getting to many codes at once and all of these sensor can,t be going bad at the same time Looking at the random misfire and the fuel trim issues map and air charge all at the same time is unlikely The olny other thing you may wan,t to check is the crankshaft pisition sensor but aren,t getting that code so im thinking fuel delevery good luck
