Yea, its not really a alarming feeling. Just a few small jolts about ever 7 - 10 seconds. My brother's 04 GTO does it way worse! His has 23K on it and the damn thing rumbles at a dead stop sometimes. I make fun of him about.
And my GTP's air is colder than his GTO
BUT!! GTO.... That car is crazy fast! it will do 120mph NO PROBLEM in 6th sitting at about 3.5K rpm. Its fun

Bad gas though >:| Premium too!
