Default Rough idle 03 GT

Changed plugs & wires Champion plugs 470 (RE14MCC5) .40 gap NAPA Belden Max Wire Set. Still running rough. As stated in many posts the coil pack dosen't fail very often. Will clean throttle plate next. My question is will i need a new gasket?

Not sure about the gasket but you should be able to clean the throttle plate with a couple squirts of throttle body cleaner while the throttle body is still attached, also on the back of the TB is an electrical connection to the IAC (Idle Air Controller) that can be a source of a rough. idle. It can be taken off and cleaned.
