throttle position sensor?
throttle position sensor was the first thing i checked, 300ZX’s will run without it even plugged in…so i was advised by Z guys to simply unplug it and see how the car runs…made no difference…cleaned it anyway, everything looked fine with it…
make me an offer 
is this the 2+0 or 2+2
2+0
take off the wing
Doesn’t look like you’re asking for motivation, looks more like you’re trying to sucker someone into helping you for a couple bucks (ie a 6 pack of beer)
