Would I be able to pull 1 wire at a time while it'* idling to see if I can find the miss?

Maybe. I have found if you have one cylinder missing, you don't notice it until high loads. I have never noticed it at idle...

This one has a clear miss at idle,and I'm hoping that when I pull each wire that one of them won't make a difference because that will be the faulty wire,coil or plug.

That does work. Just make sure that you have the proper spark plug plyers which will not damage the boot and will insulate you from 50 000 volts (wake up call!!).

When I had a miss at idle, it turned out to be two cylinders.. And a bad coil. Could that be your problem?

I was supposed to go and look at it today but I couldn't get down to see it so maybe next weekend.....so you just replaced the coil and everything was ok?At least the coils are easy to get at....I have 2 older GP'* with the 3.1'*........not as easy.

Yes, but I would still check the plugs and wires first. Then move to the coils.

Was reading up on the EGRless 3800'* in 92....does this include the supercharged engines?From what I was reading could this be a possibility for the miss?

You should have an EGR. Look for the mushroom at the lower right hand corner of the engine.
