2005 Cadillac CTS Repair Question
Cadillac CTS Fuel rail Problem
i've attached a pic this is a 2.8l but if you have a 3.6l it will be similar. you need a special tool to disconect fuel line and put a rag around it so the fuel wont' spray all over, remove the bolts and harness you may have to push thewire clip on each injector to get h arness off. then pull up on rail and injectors will come out with it. they will have clips that hold the injecotr in and lube new injector with light grease as to not damage o-ring. then reassemble.
