Cadillac Repair: FUEL INJECTORS, fuel rail, fuel injectors
QuestionHOW CAN I REMOVE THE INJECTORS TO CLEAN THEM ON A 91 DEVILLE 4.9 FUEL INJECTION?
AnswerJimmy
The injectors on the 4.9 are to be replaced,cleaning them can lead to failure of the injectors,they are what is known as multec injectors and cleaner will eat through the windings.
In order to remove them,you will need to remove the fuel rail you would also need to move the p/s pump aside to be able to gain clearance for the rail.you remove the injectors and the fuel rail as one assembly.
