Have you ever wondered how to change the back three spark plugs in your Impala. I found this video on youtube on how to change the back three spark plugs on a 99 Pontiac grand prix. I think the motor configurations on the grand prix and impala are very close and I've found this video to be very helpful. I look forward to changing my own spark plugs and saving $200 to $300.

Did you have to support your engine after you disconnected the motor mounts? And if so what did you use to support it?
