Hey, my 87 Ciera 3.8 has a horrible miss when its cold, if I feather the throttle it seems to go away after a little while, this occurs too when its warm only once in a while. So I figured I would post the problem up here so someone who knew anyhting could give a helping hand. Thanx.

you might have to get more descriptive with your "cold miss". Right off the bat I would suggest new plugs and plug wires... If you give more info, we might be able to narrow it down further.
