      I recently replaced my MAF sensor, due to age and mileage (180,000) on the original one. After cleaning the Throttle Bosy doing a TBA (Throttle Body Adaptation) the car barely idles and runs worse than before. When i finally do get the car to idle, the MAF reading is above the specifications listed in the VCDS. I also have new front and rear O2 sensors installed. Am I missing some other adaptation that I should be doing? Any insight would be greatly appreciated. I can post readings and logs this weekend if needed.

      Can we get an auto-scan, and maybe some MAF logs? Preferably both ways, with the old and new sensors.
