I was referring to the actual throttle body. If it doesn't go fully open when the pedal is floored, then there's a problem with the linkage. This may be due to broken or misassembled parts, or could just be an adjustment. You'll have to look things over to find the problem if it's that.

That sounds like what we called a throttle position sensor (TPS) in mechanic school.

Maybe. On an OBDII car a failed TPS would at least set a code and a check engine light. What else it does depends on the programming of the fuel injection system. I have no direct experience or specific knowledge relating to your year and model of car.
