My wife and I recently bought a used Cadillac Escalade. It is a 2010 with the 6.2L engine. Its throwing P0171 and P0174 at the same time. It takes about three times of starting it and running it before the CEL comes on. I threw the Matco scanner on it and i have the freeze frame data but i know absolutley nothing about gas angines and what the parameters are for normal running conditions. I looked for a  vacuum leak or anything obvious and I noticed the MAP sensor was kinda loose. I put a little Ultra Grey around it. Also i cleaned the MAF sensor but still didn't fix anything. Anybody have any ideas? Any help would be greatly appreciated.
