I just purchased my first Cadillac. 2008 3.6DI with about 50k on it. I got a great deal and love the car. I have been reading alot about the "Loud injectors" and i understand that no biggie. I have 2 questions for the people with one of these cars
1 - I was told it should idle "smooth as glass" This one is slightly rough. Not like a monster truck but it is felt.
2 - There is a pinging from what seems like coming from the drivers side back of the motor/firewall area. Its not based on RPM, because it when it starts its a very fast sound, in no relationship to RPM. I seem to hear it when RPMS fall as well. Example, when i let off the gas you hear it lightly for about 3 seconds then it goes back to a normal sound. I thought it was a lifter but it volume does not change with temperature change like a lifter. Some say fuel Pump or lift pump? Again i no nothing (yet) about this motor. Educate me???
