The code(s) you got were likely "Lean" or "Rich" codes. They almost NEVER indicate a problem with the sensor but a problem with the SYSTEM. Just reading the code(s) and changing the part(s) isn't going to fix it. BTW - the people at Autozone are Retail Clerks - they don't know crap about cars - they're sales people.

all the things you guys are talking about is what the machine says so what I am trying to figure out is what is the problem
