P0171 Code....
So I've done all the searches and it seems to be ground, air leak, or o2 sensor...
No air leak, good grounds and o2..
p0171 is lean on bank 1..
Now the weird thing if it was running lean wouldnt that mean its not getting enough fuel..
Could it be the TR6 plugs...Prob not
Like I said it just started.. The car has been on a HP tune for about 3 years with not one prob. Other then throwing AIC code which was plug ait plug related and fixed it two weeks ago with a new one.
On a side note today is the first day it happened and it smells extremely bad of fuel. It always had its minor smell from no cats but this is bad. Another weird thing is whenever I shut my car off then turn it on the next day or so it seems to drop down like a 16th-8th of gas on the gauge. I do remember reading a while back about the C5 fuel pump or something having a small crack issue.
