Car starts rough and tries to die
 

I got a 94 sc400 that just struggles to start. It seems to idle fine(at around 500) when it starts but when i rev it it seems like it wants to stick at 1000-1500rpm. Once it goes past those rpm ranges it doesn't stick but it misfires and the exhaust pops. It's also running rich. There's no check engine light but before the car was acting like it is now I've always had a code for the egr. I'm not sure if a bad egr can do this. I just got this car not long ago and don't really know about the 1uz.
