Car still won't rev over 2k

[Zsolt Kovacs]

We still can't figure out why my car won't run over 2k. It's a 90 V8q,
with 185k km.

The code says speed sensor, however the one sensor is new already. Also,
according to the manual (thanks George) it shouldn't even run if it were
the speed sensor. The car starts fine, and runs well until it hits 2k.
That is where it just chokes and losses all power.

Please help. Why are we getting the speed sensor code? Could it be
something else?

TIA,
  Zsolt
