I am having a little trouble with my truck and am limited in my mechanical knowledge.

Have a 95 nissan truck that wasnt running too well and had a little black discharge from the exhaust showing on the side of the truck (unburned fuel). Had a tune up but the issue persists... Truck seems to run pretty well however at this time other than its idling pretty fast.

Could this be a throttle position sensor or is the Mass air sensor a more likely candidate or am I off base completely?

Thanks in advance.

Nah, you are on target. Search on this forum on how to adjust and clean these. There should also be an Idle Air Control solenoid/motor that admits bypass air for idle. Check it as well.
