RE: egr valve
It'll start throwing codes. "Check Engine Light" will come on.
If the EGR valve is not flowing the PCM will use a backup timing curve that has less advance to prevent engine ping.
Less timing advance means less performance and economy.
The EGR goes into a closed loop during WOT, so it's not going to give you any gains... just helps contribute to smog by deleting it.
