Hello, my car will start up, but after 30 or so seconds the idle drops down to about 750 and the engine shakes more the lower the RPM gets. Eventually it will shut off, then afterwards I have to pull the EGI fuse/crank/restart cycle again. I have to press the throttle to keep it alive, but it doesn't sound normal at all/

The exhaust coming out the left tail pipe looks un-normal as you will see in the video. Also when it shuts off, smoke similar to lighting a cigarette leaves the exhaust?

check the maf sensor (or the map sensor if you run a powerfc)
if they get wrong readings you car will start but then flood and die...
