So I've own my 2009 I5 Canyon just about 3 months now. It has just over 100K miles and it's starting to act like every chevy I've ever owned... It randomly doesn't start like I'm not getting fuel. Then when it finally starts I get "service traction control" and "reduced power" and of course it runs rough. I get out my handy code reader and this is what I get:
P0171 - System too lean (This has been happening since day one, I guess it's the K&N)
P0651 - Sensor Reference Voltage "B" Circuit/Open (no idea what this means)
P0336 - Crankshaft Position sensor A Circuit Range/Performance
When I clear these codes and restart, the truck runs completely fine and shows no problems.
Today it got worse while I was driving down the road (in traffic), every time I pressed the gas pedal, it would try to die but it would idle fine. I shut it off and restarted it while rolling in traffic and it started fine and ran like it was normal.
I've been searching and here's what I plan on doing this weekend:
Getting the battery load tested (might be a low voltage screwing with BCM)
Eliminating ground blocks (I hear these can corrode over time)
Does anyone have any advice on this situation? I'm desperate here...
