I missed where you said it did it when revving.

Plugs, wires and coils would be a good place to start.

Ok thanks. Just checking to make sure my thought process is correct

 

Just let it idle and pulled one coil off at a time. All rpm dropped evenly. I'm going to change out my spark plugs since the mileage is so high. Anyone have a recommended spark plug? I hear these heads have an issue with blowing out spark plugs

 

Just make sure to warm the engine up a good bit before you take the plugs out and put anti seize on them when they go back.

 

hey its gonna be your ignition coil i just had same issue on my 2001 gt sputtering when i got on the gas hard long as i eased on the gas i was good then other times it would do it in that case to but about 100% sure same issue with yours to bro when i pulled out old coil the boot was seperated from the main coil already thus mis fireing
