nevermind ... friggin light back on, gonna disassemble egr valve and give thourogh cleaning, and new gaasket. im sure the unhooked hose wasnt good either. not a cheap part ( egr ) to replace

Did you ever double check the work the flaky mechanic did when the PCV valve was replaced? Here's the procedure if you have a GT or SE with 3800:

It is very important that the 2 o-rings are properly installed.

IMO the EGR valve is a good starting point. Good luck!
