I start up the truck and pull out in to the street. Whether at an intersection or making a turn, I push on the accelerator and nothing happens. The rpms don't increase, engine makes no sound - and I am left sitting in the middle of the road. I push the accelerator to the floor and eventually the engine comes to life and the truck moves forward. Happens more often than not when the vehicle is "cold" - within the first 20-30 minutes of operation. The accelerator is not linked directly to the engine through a cable but is a drive by wire. I have maintained my Tacoma meticulously since purchase including tune ups, oil changes, etc. I have cleaned the mass air flow sensor with no change. The problem still persists. It is very dangerous to be in the middle of an intersection with a vehicle that has lost power.
