Firing Order for 1999 Cadillac Eldorado
I have a 2000 eldorato ETC ,belive it is the same , where is #1 right or left of throttle body ? says # 6 is missing was told to change the plug
The bank towards the front of the engine going from passenger, to driver side is 2-4-6-8, and the bank towards the firewall is going from the passenger to driver side is 1-3-5-7. If you dont get what i mean as passenger to driver side, im saying count the cylinders from left to right as if you were standing in front of the car.
Well this is front well drive and the front of the motor is at the drivers side or that would be my guess as that is where the throttle body is , either way i am sure #6 is one of the back ones so if I chang the both of them I should be covered , see if that gets ride of code P0306 , car is running rough and get it up to about 3800 rpms it starts surging up and down ??? might be an injector breaking down ???
I know its fwd, hes a picture to help you out. It definatly sounds like a fuel problem. Check the fuel pressure, its should be around 41-47psi with key on engine off. From what saying it good chance its the fuel pressure regulator, or the vacuum line going to it.
MY bad nvm that first picture, uploading the wrong one lol...
