Reduced engine power warning & high pressure fuel pump
My 2015 CS V6 with 57500 miles has waring "Reduced engine power" on or off sometime. I replaced all plugs and coils and still get warning sometime. Is that something to do with high pressure fuel pump? I did some research and most people say fuel pump needs to be replaced. Just want to confirm before I purchase it. There are two pumps on CS and $385 each.
The two fuel pumps are one in the tank, and one on the engine - camshaft driven. The camshaft driven one is not $283. Triple that probably.
It would behoove you to either buy a tool to do diagnostics - like reading out the fuel pressure at various points in the system before throwing parts at it based on findings on the Interwebz. If this sounds like Greek to you - you may not be a DIY kinda guy and may need some professional assistance.
