Why was the computer reset?
How long and what driving have you done/drove it to reset it?
There are certian drive cycles to go threw to help aid on a reset.

some one told me to start engine turn on ac place in drive but not drive it for 3 to 5 min. then drive it some more which he did the check engine light came back on but it passed they said it was p14 & p15codes.
thank you
