My wife's 2015 F3S has been throwing P0203:codes off and on since day one. Took it to dealer and was told wire to #3 injector loose, checked connectors and plugged it back in. Now 500 miles latter it start throwing the code again, P0203, will run on two cylinders for a while and then go back to three then back to two. Any ideas?
