Bought a 06 TB with 194,000 miles on. Owner said the CEL was on. He reset the code via battery disconnect. The only code I pulled was p0107. So after some research I come up with 1. Replace the MAP, 2. Clean the Air flow sensor, 3. Clean the Throttle body. Now I have codes P0106 and P2431. I truck is now very sluggish when first hitting the pedal and hard starting. Before it would start right up and drive fine. I did notice when cleaning the throttle body the butterfly did not close completely. Not sure if this is normal. Did check the MAP connector voltage. The ground is good and reference voltage is 5 volts. Any help would be great. I did double check the clamps and connectors everything seems OK.
