Question about 2005 Cadillac CTS
What is involved in changing the spark plugs in an '05 CTS with the 3.6l? I presume the plentum...or manifild needs to come off, as it covers up the front plugs. What do I need to look out for? Any hidden surprises that will cause problems? Do the gaskets need to be replaced, or are they an O-ring type? What am I going to break getting the insulation piece off to remove the back bolt from the plentum? Any special tools required? Any help is appreciated...Thanks
SOURCE: I have 05 cts 3.6
Try replacing the cable and if it has seperate coil ingnition swap the one misfiring with another....If misfire changes with to cylinder with the swapped coil, you've found your problem.....Regards Johngee

Did you ever find a solution to this? I am having the same issue on 2,4,6. I have replaced the coils. checked the intake for vacuum leaks. I am lost here let me know if you find anything and I will do the same.

Timing belt is rated for 85,000 to 95,000 miles.
You do not want to wait for it to break.
Today's timing belt is being use to drive water pump.
3.2 Liter MPI V6 is modular.
The engine has to come out from the bottom!!!!
It will save you 2-3 hours of labor time to do ALL these work at the same time.
Ask your service advisor to replace all heater hose at the same time to avoid trouble.
Inspect all engine and transmission mounts.
This is going to be costly but it will safe the labor charge now to complete all the tasks at the same time.
