2000 Camaro slow acceleration

I have a V6 automatic with 53k miles on it and it just started acting up. From a stop while I floor it the car slowly accelerates while the rpms go up. I seems to go normal to about 10-15mph then it slows up. If I go lightly pedaled its slowly speeds up with semi's passing me on local roads. I tried flooring and holding it to see if it would clear up, but now I hear a slight hiss sound when I floor it. I am thinking it might be clogged injectors, but I dont have a rough idle or a hard time starting. Any ideas?

cant hurt to clean out your fuel system..

air filter...

I had the air filter replaced at around 40k. I am going to ge the injection system cleaned out on Saturday. I hope it fixes the problem.

sounds like a possible vacume leak???

I took my cat off and the problem went away looks like I need a new cat. I called the dealer and its still under warranty until 83k miles on the cats. Lucky Me!!! Back to normal driving...

good call on the cats, im a bit dissapointed i didnt think of that. :(
