If the first pair of flashes are spaced further apart than the second pair, it looks like code 22 from here. The code will repeat 3 times. Your factory service manual will guide you through the best way to trouble shoot the cause. Remember, don't shoot the messenger.

RACE ON!!!

Looks like code 22 == TPS voltage low.

Check the voltage at the TPS; it should read around .7 Vdc at normal idle and .54Vdc at base idle (i.e. 450rpm).

If the TPS reading changes between the base idle and any other idle, you've got bigger problems than the TPS.
