Flashing Check Engine lights is bad news. It means that the misfire is so bad that raw fuel is dumping into the cats, which spells doom for the cats. If you run it too long it will damage the cats. The problems could be numerous, you really need to get it scanned. If you can find one. It is running really rich right now. It could be wiring to a sensor such as IAT or ECT. If one of those are disconnect or damaged it would read -40 and would run like crap. Sorry I can't help more.
