2004 Escalade 6.0
Need to put a couple of hundred miles on Saturday and now a check engine light. Instead of using my Tech2 I ran out to my mechanic in case I may need parts for a fast fix. Bank one was lean and he looked the engine over. My Airaid intake tube was loose from the throttle body and was cocked a little causing a vacuum leak messing with the MAF sensor. $10 later and all is well.
