I am an hour ten minutes away (40miles) from anyone who can check my codes and fix my 2000 RX300 with 96300 (the extended warrenty ended at 96000). I have to go on a road trip and need to get it to the toyota dealer tomorrow...can I drive or do I have to pay for a tow?

This has happened three times but it was not blinking, and twice it was coils and once it was an o2 sensor...the light blinks and then is just on for a while and then blinks again...etc. There is a teeny bit of shudder upon acceleration at this point but nothing as bad as in the past..

Information from Service Manual:

The MIL will blink when a misfire occurs that will raise the temperature enough to damage the catalytic converter. The blinking may be intermittent, because of changes in engine load and the severity of engine misfire.

When a misfire occurs that is severe enough to damage the Catalytic Converter the MIL will blink during the first trip. If the condition reoccurs during the second trip, the MIL again blinks, the DTC and Freeze Frame
are recorded in memory. The MIL will be on solid once the DTC is
recorded if the misfire is no longer severe enough to damage the catalyst.

Should the MIL blink due to a misfire, the MIL will go off if the misfire is no longer detected. A misfire DTC will be stored if the misfire meets the criteria for storing in the ECM memory.
