I had the same problem with a 2001 LX. Pull the spark plug cables one
at a time and inspect for oil both inside the plug and down on the
spark plug. I had a leaking valve cover gasket and the oil was
preventing my #1 cylinder from getting any spark whatsoever. It would
be alright at idle, but would buck like a sonuvabitch when the engine
was under load. If this isn't the problem, then stick with the free
"Autozone Diagnostic" but take whatever they tell you the code means
with a grain of salt. Some of these kids aren't the brightest.
