You should check the fuel pressure and, if there is a check engine light, get the vehicle scanned for codes. The fuel pressure should run about 50 to 60 PSI when running and should hold pressure after the engine is off for a period of time.
Thank you Marc Taylor but how do I go about getting it checked?
If you aren't going to do it yourself, then you need to take it to a dealer or an independent mechanic. If you are going to do it yourself, then you need to purchase a fuel pressure gauge and check it yourself. Most auto parts stores will hook up a scanner to check for any codes on your vehicle for free.

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.

Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps

Does it have the 2.3l Quad 4 engine? If so replace the plastic piece that the coils go into, they go bad and leak spark to the cam towers and then you get a nice one or multiple cylinder misfire.
