MF3 2044295 , LDA1 4004270 = old engine.
MF3 1008933 , LDA1 2006933 = new engine.

So I changed the engine and most everything went fine. I checked the old engine and it doesn't seem to have the plug the new one has. I'm not sure if this s he reason for the code P0443. Nor am I sure the hose is the reason, its on there tight, i highly doubt there's a vac. leak there and I don know what the hose is for, its not a fluid hose. I connected every one I could find along the way. I pulled the wire harness through the firewall, and back for the new one. Instead of disconnecting all the ones on the engine/transmission.
I'm not sure what else to say, I searched this site/forum for the code and didn't find anything. The code regards evaporation emission control purge valve. I'm not sure where that is, and like I said I couldn't find any loose plugs while the engine/tranny were hanging out of the car. Any help is appreciated.
