Check the order of ignition wires to cylinders and make sure they match up. I had a shop once match #5 to #6 and vice versa and it caused the car to missfire and never exceed 4k rpms. I would hit 'the wall' around what I would imagine to be the top of 2nd gear in a standard car, but mine was automatic.
Could be a bad or poorly gapped sparkplug?
Other than those minor things I really don't know what could have happened.
