So i have a stomp test code 1224, intake air temp sensor, and have read i need to replace the whole AFM, before i do that, does anybody know what readings i should get and how to test that sensor? It has a bouncing idle for a few seconds after a hot start (like my last 318is which was partially rememdied by cleaning the icv) but i also have this code i would like to solve. Any direction would be great.
