Improcenti problems, lack of power

Hello, my name is David and my car is a BMW 316i Compact E36 of 94 with idle problems, lack of power and bad accelerator response. It is changed all the sensors from crankshaft cams, temperature, flow and draft, lambda probe, coil spark plug cables, gasoline pressure, wiring and by last diagnosis which does not give fault but gives 18º of advance on when it must be between -10º and 10º and nobody tells me why the unit advances those degrees, to which this is due and what is due and what is due to which it is due to which it is due to which it is due to which it is due to which it is due to which this is due to which it is due to which this is due to which it is due to which it is due to which this is due to which it is due to which it is due to which it is due to which this is due to which it is due to which it is due to which this is due to which this The strange thing is that by advancing the captor of the crankshaft 2 or 3 teeth the car improves significantly please someone who knows what I am talking about because nobody in 7 years has given me the problem not even BMW has been able to thank you thanks answers thanks thanks.
