I have exactly the same problem and codes you listed on my 2000 Camry 4 cyl. I replaced the plugs which had no effect. My friend mechanic said the problem is deffinitely the wires and I could also need to replace the coil pack.
Sounds like you have a problem with the spark the coil may be on its\015\012way out or there may be oil in the spark plug holls shorting out the\015\012spark.
\015\012your best bet is to pull the leads out 1 at a time and and look down\015\012and check for oil if there is oil there get a new rocker cover gasket.
\015\012if no oil refit plug leads loosely and start the car remove one lead at\015\012a time slowly and look at the spark cumming out the end off the lead is\015\012it blue? if so it is ok if it is yellow and dull you have a coil\015\012problem. also check that the spark is only coming out the end of the\015\012lead as it may be coming out the side of the lead and shorting to earth,
\015\012you can do this by slowly moving the lead around the top of the spark plug holl and see were the spark is coming from
\015\012be carfull no to shock your self as it hearts like hell
\015\012good luck
