Hello, there is something with your engine performance that is not working properly that has caused the engine's computer to de-power certain portions of the engine operation so that damage does not occur further. It can be related to throttle control, transmission operation, engine temperature or something else. Diagnostic testing is required to find out what is going on and what needs to be done to resolve it. www.repairpal.com/repair-shops
