New plugs and wires......now shuddering and cutting out.. :(
I just did the plugs and wires on friday, went to advanced auto and got some ac delco plugs and used the new wires i already had at home. And now it shudders and cuts out when i get on it past half throttle. Any suggestions?.....maybe the guy gave me the wrong plugs....

Maybe the connections to the plugs have not been "seated" correctly. I would unplug the boots from the spark plugs (one at a time) and then try to plug them back in again. You should feel that "click" to know that the connection is good. I know the plugs in the back of the engine are tougher to work on.
Oh, yeah, one other thing I do is put a dab of di-electric(silicone) grease in the spark plug boot so they come off easier the next time I have to change the spark plugs.

Check for a defective new plug, too... Sounds like a 1-cylinder misfire.

I have driven the car some more and notice that it does the cutting out and shuddering past half throttle when the car is warmed up to operating temperature. So does this sound like the wires are the problem? I dont have any heat shields on the boots either.

The lack of heat shields on the wire boots at this point (being brand new). They just serve to prolong the life of the wires. Really you are going to have to take off each wire and check the resistances through each one (one at a time). Write each resistance down, the resistance should get slightly higher with the length of the wire. If one is bad, you will notice the reading to be out of whack. Have a good look at each on for any defects and even within the boot itself to ensure that the plug seat is not damaged. Short of that you may end up pulling each plug to have a look for one that looks different from the others. Don't give up you'll find it yet.

You need a multimeter/ohmmeter. Put it on ohms, and probe from one end of the wire to the other. Write down your numbers by cylinder number, and report them here.
