      Hello everybody. So i'm having this problem with my car. After reassembling the engine bay (engine and gear box were taken off) i started encountering lot's of fault codes, mostly MAF and TB (Throttle valve control). I was suggested to get a new MAF and a new TB, but it was better to check it out first, so i took them from an other R32 that was getting a "paint job", so the guy didn't really need them much. But, nothing changed, i was still getting those faults and now i don't really know what to do. Maybe smbd bumped into this problem before. My thoughts are that its neither some mistakes in the assemble (connection problems) nor i got moist (water) in my ECM. Anyway this is a list of what i got last week, they appear randomly and all go with the "01314 – Engine Control Module 013 – Check DTC Memory" fault:

      000545- Angle Sensor 2 for Throttle (G188)
      P0221 – 008 Implausible Signal;
      000545- Angle Sensor 2 for Throttle (G188)

      P2189 – 001 –;

      Well i quess i've found the problem of the 5th cylinder misfire, not quite sure, but i believe the reason is the broken lock on the connector of the spark plug wire . Got it ordered. Will receive on Friday.

      Are you sure all grounds and hooked up clean and solid. I would check for loose ground first. Also check that you have no loose power cables.
