Then you may need to get it "live data" scanned, that way the Tech can see in real time what is going on as it is driving down the road. Check around at local shops and see of they have the equipment for live data scanning.

A flashing check engine light is warning you that the engine is misfiring and damaging the catalytic converter. Since it only flashes while driving it's misfiring under load. You most likely need a tune up. If you have over 100,000 miles on your Tacoma you definitely need a tune up!! HTH. -Jim
