when i am launching from a stop and reach about 5000 rpm the car has a serious bog and it sounds like the engine is choking, can one of you guys please explain what is going on.

It could be alot of things.

My 1st guesses:

1. Restricted fuel filter
2. Restricted air filter
3. Restricted CAT(s)
4. Ignition is weak
5. PCM is miscalculating fueling

A wide-band O2 would help to accurately indicate the problem, though.

Good Luck!

Does it make any popping noises or anything?

Could be bad plugs and wires if thats the case.

Or if there is no noise and it stops pulling it could be worn valve springs.

yes i am getting a popping sound

I'd guess plugs and wires then.

Get some Taylor wires.
