Engine power reduce turns on randomly and doesn't let me use the full power and sometimes sounds like it's going to shut off.

Hi,

This can be caused by a few things. By chance, is the check engine light staying on when the engine is running? If it is, I would suggest having the CAN bus scanned. CAN stands for controller area network. Basically, the computers/modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them.

Here is a link that explains how it's done:

Let me know if that is something you can do or have done.

Take care,

Joe
