I took off the plug covers, but dont see any oil around the plug wells. The car misfires while accelerating, usually after it's warmed up, so I suspect other coils are bad. I'm thinking about replacing all the other coils and plugs. However, while reading through the forum, I'm concerned maybe the computer is bad and occasionally not sending the pulse to the coil(s). The dealer said the status code didnt show anything. I have a few questions, and appreciate any experienced information.
1- How do I take off the coils, do I just pull them or twist them off. I am afraid to break them?
2- What's involved in changing the gaskets. The plug covers were bad enough to remove!
3- If the car misfires(as it does), no check engine light comes on. Will the diagnostic readout still show the fault.
Thanks for any information you have.

considering you have the V8 all the tasks they are doing are easily accomplished but i highly recommend tthat you shop ebay for a repair CD.
The CEL may not always come on in misfires it depends on how severe and consistent. Most OBDII worth while will show you stored codes and will test for misfire. If you have a laptop I highly recommend the scantool from autoenginuity.com. you can get a great deal if you buy from the guy on ebay. Great support and superior customer service.
