My buddy has a 97 Mazda B4000 pickup and the "Check Engine" light came on. We hooked up a code reader and got 2 codes- 0171 and 0174. The book with the reader says these are "Bank 1- Too Lean" and "Bank 2- Too Lean". Any ideas what's causing this? Could this be clogged injectors, oxygen sensor, mass air flow or what? I don't hear any vacuum leaks and all of the vacuum hoses are connected. All help appreciated.
