If anyone can get me on the right track to solve the issues I have would be greatly appreciated. At this point I took to mechanic and they removed the air filter and supposedly checked all the turbo air intakes. They put it on a scanner and it returned error codes 31, 51, 52. Which when I looked them up gave me communication error in sensor network.31. Then the solenoid the controls turbos pressure is faulty of pipes that connect to it are shot.52. Last the vacuum sensor is defective. 51.

I don't have acceleration to pass anyone that is going slow. I seem to have a bit of acceleration if the rpms are above 2500 but only in first and sometimes second gear. It's has the 4m41 engine and it is no longer automatic transmission. There is lots hills and I can only climb them in first at high rpms. I tried climbing one in second and it wouldn't go so I geared down but ended at 2k rpms and went a bit farther before it bogs and will stall. When it bogs it starts to burn black smoke. Let me know if info or pics needed. Also seems to accelerate better when cold.
