My car has been sitting since Thanksgiving and decided to drive it today.

When in 2nd, third, or fourth, anything abouve 3,000 Rpms the engine spits and spudders? It will not go any faster...This never did this before so I have no ide where this came from.

Fuel filter was changed in July, oil was changed in November...

The only thing I can think of is that in November the Catalitic converter the baffels were ratling around like they broke off inside the cat. Could this be clogging the exhaust and causing this.

Could it be the plugs in wires? If so hos could this just start happening like it did.

Anything you can think let me know please? I guess I will have to take it to the dealer and run some test.
