Default 87 Throttlebody rebuild service?

I'm looking to have mine rebuilt. Over the years I remember seeing TB's getting a machined bushing for the shaft....but I'm having a hard time locating where. I am surprised to find the throttlebody sticking intermittently towards the closed position with a fair amount of play from the shaft at 65K. It feels free when not running however when running with cruise and throttle cable removed she binds a little, if I tap it- it goes closed. I want to make it right. Thanks!

There is a guy on Ebay that rebuilds stock 48mm TB into 52mm and 58mm, you could try him out.

stay away from the ebay TB guy. his service was terrible, and he couldn't give a crap. ZERO customer service.
I think he does it in his basement, when he has free time from his regular job.

There used to be a guy here on the Forum that had a really good reputation for this kind of work. I think he went thru a divorce and seems to have disappeared from the forum. I think his name was Dave Koldus or something close to that.

You mean the mass airflow sensor, 87's do not have a throttle body, after 1984, all C4's had tuned port fuel injection. You can buy rebuilt MAF's at car parts stores.

TPI 's have a TB on the entrance to the upper plenum, it's not TB injection like the 84's, but there is a TB.
