Misfire?
 

Sometimes when im on the gas hard in my GP, in the rpm range from like 4000-5500 itll feel like its misfiring, usually 3-4 times itll miss/stumble until im out of that RPM range....only does it at full throttle that ive noticed. plugs and wires were just done about a month ago, and its not throwing a code. any ideas?

Get one of the guys around here with HPTuners (foff667, Little G, others?) to scan your car and see what it is doing under these conditions.
