Question on BMW 3-Series E36 O2_Sensor

Update to last post.

I've read somewhere maybe here car can lose power caused by :

1. Failing MAF
2. Failing O2 sensor
3. Injector problem
4. Misfire wiring
5. Clogged catalytic box

Sometimes, my car will lose power after the engine get warm. While its in the cool state, the engine will run smoothly.

Are all points I stated up there can be real for the problem i had?

Problems are :

1. High fuel consumption.
2. Lose power after engine runs at least half an hour.
3. Somemore but cant remember.

Could be a fuel pump issue or misfire. I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.




I would also perform a fuel delivery system test. Check fuel pressure, volume and quality.
