2007 350z P1502 engine code
Hey guys, looking for some guidance on this one. Replaced engine wiring and harnesses due to rats chewing my wires up. Through this the ECM got shorted out and I had to replace it with a used ECM from the same make model and year. After finally finding the part. The dealer installed and told me I’m getting a high idle code which I never had to begin with. They are telling me I need to replace both throttle bodies. They said they ran the engine relearn and te code P1502 is still showing. I have a feeling they are full of crap.

Are you sure the pins and connectors going to the throttles are in good shape? If you now have a circuit code you didn't before, i'd start there. Check the harness at both ends (TB and PCM) for any pin tension issues or damage, before you just replace 2 throttle bodies. If the code is side specific you could swap them and see if it follows, I don't know if the description points to one throttle or just in general.
