I have a 04 Taco with a hair over 100K on her. My baby has been very well taken care of but lately something has been going on. At any given speed she will just fall on her face for a moment then came right back. It is like the ignition is turned off and right back on and does not respond when pressing the gas pedal further. I thought it was related to the comp. cycling on and off but I turned the A/C off yesterday and it still did it. On the way home from work yesterday it did it 5 times within 19 miles. New fuel filter about a month ago and still does it. Any ideas?
