Question about 2000 Toyota Camry
The first thing to do is run and OBD 2 code check, any parts store like Auto Zone or Kragen will do this for free, others thing to check are the MAF sensor, clean it by buying MAF sensor spray, CRC makes this product, spray the inside of the MAF to clean out any dirt or dust that may have gotten on the wire element that is the actual sensor, another thing is replace the fuel filter if you haven't done so and check the fuel pressure at the test port on the top of the engine, it is a Shrader type valve, like a tire valve, you will need a fuel injection pressure tester for this, they are cheap, about $20, far less than having a shop do it for $50-$100. If you have codes in the computer (PCM) post them back here and I will help define them and suggest a repair strategy.

Sounds like you are overdue for a real good tune-up...
What I would do is as follows:
Replace the spark plugs with the factory recommended units (important)
Replace the spark plug wires (this is prob the real issue with your hesitation)
Replace the air filter if it is dirty.
Get the auto transmission power flushed.
Change the oil & filter.
Get an "induction cleaning" service performed.
Look for vacuum leaks on the air tube going from the air filter box to the intake manifold.
If the timing belt was off a tooth, the engine would always run bad, it would not improve "at times".
Please advise me if the "Check Engine" light is on for more info.
