My service engine light has come on. I checked the codes and it's P0171, which is the System adaptive fuel too lean (Bank 1). Is there a way to find out more specific what the problem may be? or which sensor is gone bad?
I've been looking on line but can't seem to find an answer. And i don't really want to spend over $100. just to find out when it's probalby some i can fix myself.
Any help would be appriciated.
Can email me at rj27687@aol.com

Thanks
