Seems only on cold start up and drive. In low gears especially when give gas just doesnt seem to respond right. Sometimes even a jerking feeling. Car is all stock and technician says cant find anything wrong.

Running premium?Comment

As stated on Camaro5, it's the nature of the beast. Mine became more exaggerated right after I installed a ported throttle body. When I test drove it right after the install I thought it was going to need to re-tune. But within five minutes it cleared right up. It's done the same thing each cold start up. Wiki's description was right on with what everyone else is experiencing.sigpicComment

Yep same with mine till she`s warmed up.Comment

Mine too but I think that's just the cold start in closed loop. The A/F is probably on the richer side to minimize wear on the engine on cold start.2010 Camaro SS/RS L99

My car ran like doo-doo with mid-grade. Premium eliminated all of the surging. Note that I have a V6, though.
Also, the SS needs premium according to GM.Comment

also of note, if you use lower than premium in the SS, the pcm may get stuck on the lower octane mapping... requiring the 5&20 fuse pull to reset...Originally posted by TonyNo View Post
