2000 V70XC cannot accelerate, wrong gas?

Etm for sure. Light was on already so you know there's a problem with that combined with the low idle and shaking. The abs module won't have any bearing until it degrades enough where it's no longer supplying a speed signal to the tcu, then the trans will go into limp mode.

Mine went into on-and-off limp mode for months before the ABS module went. It would be fine for days then be a problem or it would limp for several miles and stop. ABS module cured it. When the ETM went it would sputter and lose power but mostly it would surge at idle. That also went on for months and the surging got worse and worse. Then finally last January on the coldest day of a New Hampshire winter it died altogether. But I never had ETS/ABS lights as the ETM went bad. Never even had a Check Engine light go on.
