Engine malfunction after HPFP change

zimon · 01-17-2010, 06:45 PM

On Saturday after picking up the car from dealer service on Friday engine light reduced power/ engine malfunction goes on. I know is not HPFP because they just replaced it. I stoped on a light and RPM fell to 500 and went up by itself. It feels like it's choking and it's going to shut off. it starts ok.The engine sound different than usual .
Did anyone had the same thing with their car?

Could still be the HPFP. Some people have reported the replacement pump failing on the way home from the shop! Or could be injectors. Turn it around and take it back to the service guys.

It's most likely the injectors. They had to replace almost all of mine after the HPFP. I'm still having issues.
