I am all happy with my 18 city and 21+ highway, (as long as I stay below 80)

Yea the solder joints crack with age. Mine had the same problem. After a couple YouTube videos I took my cluster apart and fixed those connections and good as new
Ok I will research and also I got the maf sensor, cleared codes too will drive wed and see what mpg I gain
