can someone tell me what this part is called on my throttle body? high idle problem.

1999 Tacoma V6 3.4
apparently the shop I took my truck to for a high idle problem says this part is the culprit but even the dealers say it's obsolete.

and just FYI, I had the throttle body re-bored and that fixed the high idle for a couple months and then the issue crept back again. sometimes the throttle seems like it's sticking and gets stuck in a high rpm.

things I've done/replaced:
cleaned MAF
new TPS
TB rebore
checked for air leaks
tried a new IAC
new thermostat
new wires
new coil packs

all that said, I just need the name to know where to find a new one of these. it's cracked and needs replacing regardless if it's the problem or not.

 

I've always called those things a "dashpot" even back to carburetor days. Looking at my info now, I'll get back to you.

 

Looking at this picture, is it the "throttle opener"?

 

Looks like the

thanks for the response. I assumed the dashpot was the metal conical thing on the opposite side of the TB connected to a small vacuum line. guess not.

 

many thanks. hopefully i can find one that matches up.

 

They are available, look at a Toyota site on line just check your year, that p/n might be the correct one, just verify it.
