I am looking at pulling the injectors on the 81 and having them cleaned. I have heard Injector Services does a good job for $17 per.
What are the WYAIT items or parts?
Thanks,

I'm doing the same to my '82 as the rubber appears to be cracking. I have a thread on it, do a search for "Redoing the Hoses". Because I have a serious **** retentive problem I'm replacing everything rubber under the plenum, overkill I know. I figure it is one of those pay me now or pay me later things.

There is a lot of grey area with the term "OB"
Many consider it only applies to CIS 928's, where other people include any non S 928...
If you send out the injectors to someone like withhunter, they replace the o-rings, caps on them.

Hmm, I started that project back in 2004. "Pull the injectors to have them cleaned" is how I started.
When this job was complete, I ended up pulling the spyder & replacing every piece of rubber, gasket and seal, and hoses. Pretty much everything above the heads.

I second Hacker's motion to replace rubber.
I did this job last summer after the breather house broke off in my hands, and it was obvious that it would be a sincere bitch to get the bottom portion of a new hose connected, since it connects at the bottom of the throttle body.
When I took it all apart, I discovered that the rubber connectors between the spider "body" and the "legs" were about as flexible as glass. They broke like hard plastic in my hands, so I replaced these. If you pull the spider, you MUST replace the gaskets between the intake tubes and the head.
Also...while I had it apart, I noticed that three of the little tubes that lead from the rail to the injector were seeping fuel everywhere, including on top of the head
. Replace these!
As to injector rebuilds...I had mine done by Rich up at Cruzinperformance in Michigan. $15 each, and he flow-matched them.
Best of luck- and post some pictures.
N!

Thanks for all the great information.
I wanted to send the injectors out for cleaning because I want them tested to see if I need to replace any off them.
After reading everyones feedback, I figure I might as well do everything while I am there.
So here is my list so far:
Injector cleaning
Replace the rubber (maybe braided for the 2 main fuel lines)
Replace vacuum lines (I knew I got a one of those kits for a reason).
Replace intake gaskets.
Replace, plugs, wires, rotor and cap.
Misc: Heater valve
Powder coating... hmmm .... I'm on the fence on this one.
What is missing?

If so, they say it helps in cooling!

Thanks to everyone for all the tips and info.
