Could this be a governor? Some kind of speed sensor? How am i supposed to take it down the track like this (lol!) and how can i fix this? Thanks in advance!
 
Is this another Why isn't my V6 faster? question?

If your car has a POS V6, that is as fast as it can be expected to go. If it has a V8, you have a problem.
 
When the car dies, turn the key off for a few seconds then turn the key
to the run position and listen for the fuel pump to make sure its in
working order. If you don't hear the fuel pump, its probably bad. If the
fuel pump works, it could be spark related like bad coil packs. When the
car stalls, does the check engine light iiluminate? If it does take it
to a dealer to have the codes read..
