No, we have pretty much eliminated the fuel rail / starvation theory. It's not physically possible.

 

i think i have a similar problem i have about 12,900 miles on my car and when i accelerate normaly the car will like skip a beat usually around 3500 rpm (i shift at 4k)
almost feels like the clutch sliped this doesnt happen often. and if i go WOT it does it closer to redline tho like 5800rpm. i have always dismissed it as a clutch problem, and my clutch does slip pretty bad sometimes

 

Have you cleaned your maf? or at least had a look at it?
i had a similar problem.

Can of electrical cleaner and a Q-tip....and poof. pullin hard again.

 

ok everybody. First off i have cleaned every part in the car i can.nothing has fixed it yet. mine studders no matter how hard or soft i accelerate. it has a rough idle and now noticable power loss. i really want it fixed so i can put the stage 2 on it.

The dealership call me today and told me that the regional manager want me to show him the problem. it is funny though as they told me about a guy that bought a brand new one. he told them he wanted a stage 2 kit put on it before he takes it from the lot. The funny part about it is he told them the the brand new car has the exact problem i do before and after the stage 2. they are now saying it is probably a calibration problem. i will keep everybody informed. fill free to send me an email at camaro.randy@gmail.com
