It's actually blinking, or it comes on and goes off type of blinking. If it's actually Blinking for a bit, that's REAL bad. Like don't drive it, you'll mess it up bad.
It still seems like a computer/sensor issue. Sounds like you've eliminated all the sensors that would cause it. Have you checked your O2s? if the car is reading too rich it will cut the fuel and cause you to stall.
