That's exactly how my 84 380sl acted when I needed a new O2 sensor. The
O2 sensor will only start working when the exhaust gasses have heated it up, so it is inactive on a cold engine. When hot, it would send a wrong signal to the computer which started "dumping" fuel......12 mpg. For a 380 that is way off.
