Alright this just started happening about 1000 miles ago, the car currently has around 35k miles on it. It has been occuring a lot recently. This happens at any speeds to. For example, I was driving home, at 20 mph foot exactly on about 20% throttle not moving it at al, 1500rpm and the car will go 1500 1000 1500 1000 1500 1000, than it will accelarate like it should. This usually happens in the less than 2000 rpm range, but occurs at any speed. It will bog for like 10 seconds, back n forth, than finally accelarate. Any clue? I always run preimium gas and take real good care of it. Kind of weird, but any help would be greattttttttly appreciated. Thanks guys.

Check your ground wires.

Mine had the same problem. I never isolated it, but when I changed out the wire harness, it was gone. I always thought it might have been the CAS wires or the TPS wires being messed up on the way to the ECU. But with your mileage you shouldn't have a bad harness at all. Maybe check the sensors I talked about, and also check for loose connections.
