Symptoms sound strangely like a plugged up cat to me. Not a lot of misfiring or sputtering but no power under load. The ceramic core cats can overheat and crack apart due to really poor fueling and timing or sometimes just from getting whacked by a rock or something. a loose piece of core can shift and lodge slightly sideways and it can cut off most all flow.
