Evan,
I think your car is trying to tell you something. Here's some info. I found some time ago (can't remember where) that might help.
How to read diagnostic trouble codes:
1. Stop the engine.
2. Switch on the ignition without starting the engine.
3. After approx. 6 seconds, the 'Check Engine' light goes out for an instant before lighting up again for 3 seconds. This 3 second flash is a warning that the actual flashing code is about to start.
4. The flashing code consists of a number of short flashes lasting 0.4 seconds. The 'Check Engine' light goes out for 2 seconds between each new flashing code (if there is more than one fault).
5. After the last flashing code, the 'Check Engine' light goes out for 3 seconds before lighting up again for 3 seconds, after which the flashing codes are repeated. Readout continues in this way as many times as you wish.
Number
of flashes Function
2 Manifold absolute pressure sensor
3 Temperature sensor, manifold
4 Temperature sensor, coolant
5 Throttle position sensor
6 Oxygen sensor
7 Adaptation
8 Purge valve (EVAP valve)
9 ECM, internal fault
