It's the 2002 German version of the Corsa, it wasn't made here in America.
It works fine for the first 10 km or so, then it'll suddenly stop accelerating, as if I weren't even pressing the pedal, and I have to restart the machine and it'd work again, for at least other 100-500 meters before failing again. It usually happens when I release the clutch to shift gears, or when I stop accelerating and try to accelerate again.
I've already changed the oil, the fuel and oil filters as well as the sparks, the injection system is clean. I've also checked the pedal and it's ok.
I have since tried with about 5 different people who claim they know how to use a scanner but all of them but one said the scanner didn't find anything, the last one, however, noted that it was receving bad signals from almost all sensors, so he thinks the computer is actually bad. I also asked Scotty Kilmer at his Youtube channel and he also suggested it may be a faulty computer. So I think it may be the issue, wether it can be repaired by "re-flashing" it or it should be replaced I don't know.
What could be causing this?
Solution here: Gas pedal not responding
