Rep Power: 0

After cleaning Throttle Body (not took it out, was cleaned on location - also, did not open the flap by myself, I turned the car on - electrical part -, and kept the accelerator pressed to keep it open (the flap opened by itself) and EGR (took it out and cleaned, but only the mechanical portion, and used the FTP to put it back (16ftp if I remember)), cannot have the car under 1k rpm in idle. In addition, keep getting the PO0507. Took everything apart 2X already, trying to find any unplugged hoses or cracks on them. Any suggestions before I have to recur to a mechanic and put some $that I do not have now? Shpuld I change the EGR or the one inside the air filter box?
PS.: I found out that the air box was broken sometime in the past and gluded back again (mark on the box were inside it, with some melting plastic in it)
Any help would be really appreciated
Thanks
