Not sure either tranny or some sensor
My 99 Volvo was really sluggish when I got it
an a few months into owning it sometimes it
will not accelerate or rev. It will idle forward or
backwards but it won’t go like my pedal isn’t
doing anything when I press it. Unplugged TV
e mass airflow sensor and i feel like it has its
original power but it makes some nasty metal
noises when I accelerate or when it shifts but
it’s not jerky or a tough shift just noisy
