So i went to pick n pull there was not 1 300zx with tps intact(hot item i'm guessing) but there was an 85 maxima with a manual tranny i got the TPS off of with connector and length of wire, anyways i soldered in new connector and installed the maxima TPS. started up the z and it started to idle at 2000rpm, 1 minute later around 1400 warmed and it was back to its normal 1100. it stopped bucking and jumping when i let off the gas and the idle although high is stabilized. but 2 probelms remain the high idle and when i give it full throttle and let off, even when i clutch to change gear the rpm hangs there for a second it does not have to be high rpm just full throttle. thanks for all the help so far.

Id try squirting some PB blaster (or any type of liquid wrench) down the throttle cable to oil it up, then get some carb cleaner and clean out the TB area with some paper towels. It sounds like you have a sticky throttle cable or throttle body, try that stuff then let us know what happened..
