Default Help me ID these parts ???

HI Friends,


I'm replacing Throttle Parts and Sensors. However, there are a couple of parts i don't KNOW (can someone help me ID THEM)???

This is a D21, 4CYL model that i am restoring.

I labeled the parts in a diagram indicating the following;

Part A. there's a spring that controls a 'small piston value' below the spring. What is the Piston Called?
Part B. I know the Mass Air Sensor (i just changed)
Part C. Don't know ???


Can anyone tell me what these parts are?


Thanks very much

that looks like the "thermo element" (16391-12G00)maybe called a "wax kit" it pushes the fast idle cam, if you have a high idle, chances are this is bad
2nd pic, looks like FICD solenoid (16196-86G00) hope it helps
(both part #'s are for a 4cyl)

Cheaper? It's hard enough to GET parts for those TBI systems. The last year they put them in Nissans, at least in the USA, was the 1989 model year.

The up and down idle is a common struggle with these systems. There are a few possible causes, including even a slight vacuum leak. Good luck. You might get it stabilized. Sometimes it's tricky.
