P0174 Lean Code Bank 2
Ok, I know there has been several threads on the lean codes (already searched 
) so please bear with me during my personal crises!
I have an 08 LS3. It has a Vararam (1000-1200 miles on it) and a 160 degree t-stat (300-400 miles). The car has a little over 18000 miles on it.
This morning, I am on my way to work after the car has been sitting for 6 days. The coolant temp is about 90 degrees and I get the CEL light pop up. The car runs normally and heats up to 175-180 degrees like normal.I come home after work (light is still on) and plug in my scanner and learn that I have code #P0174 Fuel Trim System Lean Bank 2.
What would cause the code for one side? I figure that a faulty MAF sensor, air leak between the MAF and intake, or a vacuum leak would cause both banks to throw a code. Should I take it to the dealer or is there something that I should trouble shoot before taking it to the "pro's"?
TIA
