If it's not too expensive, I'd replace the PCV anyway if it's gunked up like the throttle body is.

 

Still trying to locate the pcv, I'm getting further though, I've replaced the EGR with a new one, no coding required, took out for a long drive, had my obd device in, it reported back. Throttle actuator stuck open, I already had that out and cleaned it, so I ordered a replacement, used one, opened it up, and it had so much carbon build up in it only after 2 days driving since I cleaned it, it was actually worse than when I first took it out. Nevertheless I've put in the replacement, no coding required, It's not smoking but I'm not sure if that's because I relieved the pressure from the coolant tank the night before. It did smoke after egr was in and someone told me it might be the gasket and the pressure from the coolant might be leaking in. Real test for smoke will be tomorrow. No doubt in 2 days the throttle will get stuck again. Think I need to repeat the process 10 times to try and get as much crap out as I can. Seems better though.
