I have a 1993 ford taurus 3.8L V6 GL automatic. I retrieved these continuous memory codes from my car: Code 157-mass air flow sensor fault,low voltage. Code172-HEGO(HO2S) sensor fault/lean. Code 452-vehicle speed sensor signal fault. Can you tell me what is wrong with my car and how do I fix the problem?
