skip/ sputtering in the engine while Idling?

[97SHO]

hey, just joined this forum. great place!

had a 93 SHO, traded it in for a 97 automatic V8 and love it more.
question is, while idling like pullin up to a stoplight after driving hiway or something, once ive stopped movin and the Rpm's have settled, you can hear a slight sputter every few seconds. Almost like one of the plugs mite be fouled. Where should I start trying to diagnose this? It runs fine once acclereating and cruisin though.

Try going to the V8 Section of this forum...But i can tell you that it is most likely a Coil-On-Plug unit. My car is doing the same thing,and has for about a year now.... Also,you should change your plugs while you are at it. I changed mine at 66k,and they were horrible.
