My 06 was parked about 2 months and when I first started the truck, the CEL light came on. It idles a couple of minutes and shuts off. It was running very well before it was parked. I put a code reader and the codes are P0607 and P2107. Thanks in advance for any help I could get.

P2107 = TAC module processor error
