Q: No power. Only uses bank 2 to fire

asked by on October 30, 2016

Hi guys. I got a 335i. The customer complaints was the engine warning light. I diagnosed the car only to find that it is out of timing, got special tools, I timed the car I started the car all was well then I switched off the car when I started the car again it didn't have power it is misfiring when I unplug coils from 1 to 3 the car doesn't respond when I check the spark it there, I swapped the coils around still nothing, so basically the car is only using 3 cylinders 456. Can it be the MAP sensor on the intake manifold?

My car has 25000 miles.
My car has an automatic transmission.
