Hi guys the other day my check engine light came on then it happened the next day, also both times it went back off in a few minutes but now I have a code 71 for EGR system in my computer. Both times when it happened the car ran the same. So I am not too concerned but I am trying to tune up the motor and am concerned as to what sensors this could be identifying as bad or what it means???? This isn't for the o2 sensor correct I believe that code is a 27? Could it just be a dirty throttle body? What exactly does the EGR system include? Any thoughts.....Thanks guys......

Also I have a wideband innovate AFR gauge hooked up and my afr range is 14.1 to 14.9 at cruise 3,000 rpm 60mph. Now I can't find anywhere if it is normal for the AFR to fluctuate that much at cruise? It also fluctuates at idle 14.4 to 14.8 I am guessing it is normal. Anyone have any professional tuning experience? Thanks again......
