I have a 2011 camaro bought not running was told the engine in it was new. Took it to the dealership to have it fixed. They added a bunch of new parts to get it running. They said the ecm has a 2 point connection and the engine has a 3 point connection, so it's not compatible. The car now runs but 3 injectors are wide open dumping gas. Is there a part that would be able to make the connection or does anyone have any ideas on what to do?
