FI assistance, High idle Options

[watsonrx13]

OK, I have finally gotten my second project car running.... The first time since I've owned the car (purchased 2 1/2 years ago)... (IMG:style_emoticons/default/driving.gif)

Anyway, I've done the following to the '74 2.0l engine:

New:
Spark plugs and wires
Distributor cap
Points and condensor
Vacuum and fuel hoses
Intake runner boots

Other:
Tested and rebuilt fuel injectors and new seals
Timed the engine
Adjusted the valves

I hooked all vacuum hoses, per AA's diagram. When I started it, it ran at 3000 rpm. I disconnected the AAR and plugged the hoses. I've gotten it down to 1500 rpm, but it was 'hunting'. I soaked the AAR valve overnight and washed out the PCV with carb cleaner. I hooked both back up, but it ran at 3000 rpm again.

So my questions are:

1. How do I test the AAR valve to verify it's working?
1a. If I remove it permanently, do I just plug the line to the CSV and wrap the electrical wire (the plastic plug is missing)?
2. I've ordered the TB gasket, do I need to remove the runners before I remove the TB/base?
3. After I remove the TB/base and check for pin holes, anything else to check?
4. Any other suggestions?
4a. BTW, I tried spraying carb cleaner around the TB, injectors, runners, but didn't hear any difference in the engine sound.

Also, I researched this subject and found Jack's (championgt1) posting, but there was no resolution, at least in that thread...

Update:

Well, I didn't work on the car this weekend, I'm still waiting for the TB gasket to arrive...

Anyway, I noticed in one of the ads that someone was selling the phenolic spacers for intake manifolds and they mentioned that some of the spacers were missing the gasket, so I got to thinking. When I 'cleaned' these spacers, I removed a paper gasket material, but didn't replace, so can this be part of my vacuum leak issues? If so, can I just make a paper gasket and attach to the spacer?

Hi Rob,

Good subject!!!

Who makes the TB Throttle Body Gaskets?? I need one & can't find a supplier on the vendor list for my 1974 2.0 liter F.I. re-do.

I am also checking out all my AAR valves & will probally need one. They are expensive & wondering who has the best rebuilt prices & quality??
I was thinking Otto's or maybe AA.

FYI: I just purchased a $75.00 dollar "Vacuum Line Kit" from AA and dissappointed they are not supplied in factory color anymore. They are all black/grey standard (correct) hose sizes without instructions in the package. I need to call George and tell him about this issue. Now I have to do a search on the subject. I am in the process of dyeing the hoses with the the proper CW colors (redish, brown, green & standard colors). (IMG:style_emoticons/default/mad.gif)

Yea Tom, I was disappointed also about the color of the vacuum hoses I bought from AA.... let me know what you're using to dye the hoses....

I'm still soaking my AAR valve, hoping it will unstuck the valve. The base fells like it's heating up....

tod914 had some of the TB gaskets made, he's in the vendor section.

Rob,

Thanks for the info.

I went to a local fabric/sewing center to buy dye (red, brown & green). The ladies in the store gave me the royal treatment because I was the only guy in the store.
Note to our single guys, great hang out because the store was full of hot looking women. They all wanted to help me! (IMG:style_emoticons/default/rolleyes.gif) I'll post a photo of the completed vacuum line kit when completed.
