grab your volt meter and read this

you should have around .9 volts when the TPS is closed, around 5 when WOT. if you have an old analog volt meter, use that and slowly open the throttle to see if voltage increase is steady without dead spots or abnormal readings. analog volt meters with the needle show fluctuations better than most digital meters, altho a digital works too, just be more slow when testing.
