Do you know what the TPS is?
It's the black 3-wire sensor on the passenger side of the TB. There are two flat-head screws holding it to the TB, which when loosened, allows the position of the TPS to be adjusted.
It's a tedious task to get it right sometimes, however, it's perfectly achievable.
Loosen the two screws slightly, just enough to let the sensor move, but where it stays in place when making your adjustments.
You should shoot for being under .42 at idle, and make sure you're above 4.6 at WOT. This is ideal.
If you're currently reading .72 at idle, your car should be slobberingly rich down low, causing low-end bog.
By all means, get that checked and fixed, and you'll probably notice a slightly better response off the line.
