bank 2 running lean
Ok so I started up the road notice the truck shuddering an thought it was missing tromped on it an the light came on. Programmer says Po174 bank 2 running lean. I sprayed everywhere I could think around the intake an vacuum lines with carb cleaner an sprayed the map sensor with electrical cleaner no luck so far. Oh an change the air filter.

all the plugs on the left side were black an #7 coil pack was bad an 02 sensor. Think it was leaning bank 2 out then when the coil pack went bad it caused the chaos lol. seems to run fine now
