With the key on but the engine off you measure voltage between the RED/WHT wire and body ground, with the throttle closed, bolts for the tps loose, rotate the sensor until it reads 0.5V with the throttle closed. Tighten the screws on the sensor and open the throttle all the way and at WOT it should read at 4.5V, if it's a few millivolts off don't worry. You're gonna need a digital multimeter and a back probe kit to probe the backside of the connector on the sensor.

OK I adjusted my tps to the right volts but my94 Honda prelude is still straving for gas an bogging down what could it be

Any other codes? Map sensor? Timing correct?

Pull your plugs, take a pic of it and post it up.. Might no be getting to little fuel maybe to much. You should check the fuel pressure, timming, all that good stuff

It doesn't act up at first it drives perfect until it heats up real good an then it stops taking gas for a sec but then I get gas then it stops taking it again

I've changed my tps an adjusted it right an my car is still not taking gas it has to do with the Tom's because they go up an down when they go up I get gas when they go down it stops getting gas this is on a 94 Honda prelude
