A flashing check engine light usually means an engine misfire. It's possible that you got a bad batch of gas, was it a discount gas station? I would avoid driving the car past 4000 RPM until you can get some good gas in your tank so that you do not risk damaging your catalytic converter.

Mass Air Flow sensor! Just remove your air filter cover. Go to Auto Zone and purchase some solvent. Spray past the air filter and it should correct the problem. If not, replace the Mass air-flow sensor. This is commonly mistaken for an oxygen sensor. Mine did this and I followed these steps and it fixed the light. BTW, the light stayed on for 5 years before I fixed it. Never hurt anything. It's normally something to do with emissions. Dummy lights. :)

Well it is a common problem with Toyota paint jobs. Unfortunatly a simple wax wont stop this from continuing all though it will hide it from site for a while. The problem has to do with the factory paint job, so a repaint (by Maco or any other botom dollar body shop) will only be a band-aid fix, and will most likely rear it's ugly head somewhere down the line. If you intend to sell the car this may be a way to make it look sharp and easier to sell. **** if you intend to keep it I would not sugest it as you will most definatly be dissapointed as a repaint is only a temporary fix for this issue.
To thoroughly fix this issue you would need to have the car professionally stripped (at least down to the collor coat) and repainted. This will be expensive, and most likely will cost more than it is worth for a car that old. I would start by checking to see if there was a factory recall on the paint for that year, make, and model.
Good Luck!
