Me again...forgot to add something....BOG PROBLEM???

I have a 2000 3.8L camaro. Well geezo peetzo!!! I noticed I had a problem with my car one day when I was entering the freeway. I stepped on the pedal to catch up to freeway speed. Then it seemed like my car was bogging. Like when you press the pedal all the way down, it seems like my car is just like, "Don't even try." I can compare it to when person is walking their dog...The owner walks faster but the dog pulls back because it doesn't want to go faster. I hope this paints the picture for anyone who comes across this. This is like the first problem I ever had with my car!!! HELP!!! SOMEONE!!!
I FORGOT TO ADD THAT MY CAR WON'T REV PAST 3000 RPM...maybe my mass air flow sensor?

I have a 1994 Camaro and i had the same problem in january. When i brought it to a mechanic, i was told the ignition coil was bad. i think it was 300 to fix. he also changed my plugs and wires
