If I quickly step on the gas my car will stumble a couple times then rev up smoothly. Other than this the cra runs great has plenty of power and idles very smooth, its just when i quickly step on it. I just replaced the tps, what else can this be?

is it an automatic or a manual? If its an auto, it could just be downshifting, which might be what your experiencing. Just a thought, I'm no pro.

It will do this even when it is in park, or in drive

check your spark (ie: plugs & wires)

I shall do that. Thanks alot

I have a feeling this is maf related.

97_3clipse is right, check the spark and the wires which I would replace anyways because they are probably due.

Also consider changing the fuel filter, alot of things could cause the car to stumble, even while your checking over things why not change the air filter.
