i never get a check engine light
i got those codes when i did the jumper thing to start diagnostics, and i looked up the code value on a generic EEC IV web page i found .. so it should be a valid code
i belive the EGR is stuck open, and it should *run* fine with the egr blocked off at the intake. i'm not going to leave it that way, it's just an easy way to check if that's my problem or not .. block it off, go for a ride, see if it still stumbles.
i'm postive on the code, checked it many, many times and i get the same code with the key on, engine off test and with the key on, engine on test
