P0507 - Throttle body, MAP, MAF sensors and EGR cleaned - HELP

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), but since it is all the way before tje MAF sensor...
Any help would be really appreciated
Thanks
I am re-posting it here since for the 1st time, I did not get any replay after posting a question - HELP

Re: P0507 - Throttle body, MAP, MAF sensors and EGR cleaned - HELP

As i said, I did it all over again. Went to Autozone and bought a MAF sensor cleanner Spray and Throuttle Body & Intake Cleanner Spray. This time, I took out the Throttle Body, dismonted the MAP sensor from it, and cleaned both using Eletronic Cleaning Spray on the MAP sensor and Throuttle Body Cleaning Spray on the Throutltle Body. Also, took my time after that and cleaned the MAF sensor and EGR; I cleaned the MAF sensor with The MAF Sensor Cleaning Spray. and the EGR with the Thrpttle Body Spray. Mount everything back, got an Spill-Free Funnel, and follow the instructions of running the car for purging the radiator/coolant system, and idle relearn (i had forgot to mention that I changed the radiator a week ago). Car seems better, but the P0507 is back, and the Idle are never bellow 1k RPM (witg the radiator fan, get 1.2/1.5k RPM. I have a Ancel FX2000, but seems that the parameters are normal. I am goi g to run a full scan and get each parameter to try to compare - this is making me crazy - HELP

You probably have to do an idle relearn. Here’s a pretty decent thread - for a CRV but the process should be the same.
