Thanks for asking your question. I will try and help you out.
128 only indicates there is an engine diagnostic code. Unfortunately it does not specify which code. I am sorry.
Pulling flash codes with cruise control switches is an option that's not available on models after 2007. In order to find out exactly what engine code you have, you will need to have a service tool connected to the engine and the ECM read. I am sorry. I wish there was an easier way.
Please reply back if you need more help or have more questions. I am happy to assist.
