Throttle body rebuild or replace?

[Ant_mant]

Hey Guys!

 

The cold here in Philadelphia has delayed my work on my 88 Comanche project, 4.0 5speed. I got the slave cylinder put in and the transmission back in about 2 months back and figured why not try to start her up. I bought the truck not running and it hadn't run in 3 years. Well not surprising, didn't start. Cleaned all the ground, and electrical contacts. No dice. Everything having to do with ignition looked brand new, obviously someone had tried to start her before. What the missed? Crank position sensor. Put a new one in and tried to start her up. She lives again!!! Cranked up on 3rd try. She is running rough and over revved to 3000rpm but i am not all surprised. Its been a while since anybody loved her.  Probably will need a new IAC. Any other thoughts on the high rpm?

 

My next task is to fix the throttle body. The spring does not release. if i hit the gas it will stay in position. Tried soaking with pb blaster, didn't seem to help. My question is should I rebuild it? How do I rebuild it? does anyone know where to buy a new one. Only ones I have found thus far are not Renix compatible. I would almost rather replace than rebuild but if i cannot find one, that is not an option. Any input would be much appreciated.

 

Thanks in Advance,

 

Ant

Your best bet is sourcing a used one from a junk yard or posting up in the "wanted" section here.  Finding one that is in working order shouldn't be hard at all and you can get one relatively cheap. 

 

eBay may even have a few posted, often you can find them with the sensors still on it that you can set aside for some spares.

try to clean it thorughtly first... if still doesn`t work as it should, you may need a HO adapter, as you are more likely to find  used HO for cheap...

I should have a couple renix throttle bodies would sell one. They have been sitting for years.

Do you have a link to where one of these can be found?

can`t find an specific one in ebay, most come as spacers for HO manifold to HO TB....but it`s not difficult to make one with common tools, i made a similar thing out of wood to mate the renix TB with the mixer for my propane setup

Just get another Renix one. No need to get off on another tangent with adapters. 

 

And sell your old one to www.strokedjeep.com.

 

That's Leigh Performance Machine.

 

He needs core for Renix throttle body boring.

There's not much there to "rebuild"
