I tried searching but couldnt find anything similar to what im dealing with :(. I have my car currently stored at my parents house until me and the wife move out of our apartment for a house. I have probably only put 500 miles on her in the past 2 years mainly because i cant keep it at our complex due to limited parking. I stopped up this past weekend, put a fresh battery in and took it out for about a half hour. The problem im noticing is my aem a/f gauge is reading 17.7 and higher or just ---. I know the gas is not the freshest in the tank so that cant be helping, but im just curious as to if the sensor is just plain bad from sitting so long? My egt's are normal even though its reading high 17's or just ---. Which leads me to believe the sensor is just crapped out. Any info or help is greatly appreciated, thank you :)
 
Check for exhaust leaks & test the sensor with a rag & gasoline.
