sounds like it's running pig rich, chts can make the car think it's cold when it's not which makes it run rich, might want to look into the knock sensor as well, on the l-jetronic cars an open knock sensor also casuses rich condition

i tried unplugging the the mafs while the car was runningand the car just tottaly died.tried adjusting the distributer,it reacted but not badly.adjusted tps sensor while it was running reacted to adjustment,and flopped when i pulled the plug.all good fuses.getting proper voltage signal from knock sensors.curious,could an O2 sensor cause that... but im not throwing any codes?
