reving up and down plus dies
#12
The center wire of the TPS sensor is the output. Set meter for DC volts. Push the red meter probe into the back of the hole for the center wire, with the sensor plugged in. Put the black meter probe on engine ground. Turn the key on but don't start. Observe voltage as you move the throttle lever by hand. If it doesn't come to 0.4 volts with throttle closed, loosen the screws holding the sensor on and rotate the sensor relative to the throttle body.

revving could be 1 of 2 things
1) vacuum leak (basically an air leak letting more air into the intake manifold from somewhere other than the throttle body)
2) air in the coolant
the d16z6 i thought had a bleeder screw. my d16y8 doesn't, so I swapped that part with one from the old motor. otherwise, with your engine fully cooled, start your car and take your rad cap off. squeeze the upper hose, sometimes you'll see an air bubble. constantly add coolant and squeeze random rad hoses until you're satisfied.
but replacing the coolant outlet port on the front of the block with one from an earlier D-Series motor makes life a lot easier.
I thought my TPS was bad so I replaced it and still had the same issue. ended up being a combination of bad spark plugs and air seeping into my coolant.

For a quick check, park the car on level ground and wait until the engine is completely cold. Then open the radiator cap. The radiator must be absolutely full to the top. If it is not you have to bleed the air out.
