Hello again.I have one BMW 318 is E 36 M42 1995, 103 kw,aprox 350 000 km.
In this moment all 4 cylinders have the piston rings changed,cylinder head rectified ,this job I did it due Rh,the metter with ignition system was before I was overhauling the engine. Oxygen sensor,MAF, knock sensors ,camshaft sensor,inlet temperature sensor they are new.Regarding the fuel system,all the injectors overhauled,fuel pump changed,fuel pressure regulator and the sensor from the injection rail changed as well. On the tester is showing me the "rich mixture" code,the engine is running ,but the performances are very low,the car is running with a lot of fuel,exhaust gas is clear,once I press the accceleration pedal the engine is getting chocked. I speak with my mechanic witch I done all the jobs ,and we changed and checked almost everything we thought that could be the reason,but no efect. I love my engine and I would like to make it run properly for this reason I applyed .Thanks ,maybe we can find some answers.
