I am looking into buying a 1990 Bronco with a 5.8L engine and need help.?

The seller says it needs smogged and he thinks it's the EGR valve. When it is cold it runs fine but when it warms up it cuts out. Does this sound right? Also how difficult is it to change the EGR? I know in my Thunderbird it is pretty hard to get to. Thanks in advance for the help.I am looking into buying a 1990 Bronco with a 5.8L engine and need help.?
I don't understand what 'smogged' means, but it could be EGR or carbon build up in the EGR passage. It could be one of various EEC sensors sending poor info to computer or possible the TFI module on the distributor. Does the vehicle fire right back up after it stalls?
