Bruce:

I got the same exact problem...

My AAR valve has the passenger side fitting attached to the fitting on the top of the air cleaner so that it sucks fresh air in when the AAR is open...The drivers side of the AAR fittings goes to the white plastic fitting the fuel enrichment injector goes into in the TB plenum...

When the AAR valve is open it uses vacuum to suck in raw air to mix with the fuel from the injector...In essence, it creates a vacuum leak until the AAR closes and brings the RPM down to where it's suppossed to be...My AAR works and closes completely but my RPM is still at around 1100 to 1200...Sometimes it hunts ( 900 to 1100 RPM) so bad, she dies...Starts right up and runs OK, but just won't idle...

I am going to re-time the "Hot" motor to 27 degrees but with the retard hose connected to see if that makes a difference...

2-OH!

Serious! (IMG:style_emoticons/default/smile.gif)

The car runs different at 3/4 warm, than it does at warm.

You shouldn't hold your car @ 3500 cold anyhow. (IMG:style_emoticons/default/wink.gif)

I can't help but be amused by this little (shitt'nfuck'n) car (IMG:style_emoticons/default/rolleyes.gif) but I luv it (IMG:style_emoticons/default/wub.gif)

What's also amusing... I posted this exact same thread on the Bird Board and received 2 answers....

both were from Alfred (IMG:style_emoticons/default/laugh.gif) and all it said was to down load a pdf. on D-jet maintenance (IMG:style_emoticons/default/finger.gif)

It (he/she) makes me laugh (IMG:style_emoticons/default/laugh.gif) (IMG:style_emoticons/default/laugh.gif) (IMG:style_emoticons/default/laugh.gif) (IMG:style_emoticons/default/laugh.gif) (IMG:style_emoticons/default/laugh.gif)
and I luv it too (not him/her) it's the total amusement (IMG:style_emoticons/default/aktion035.gif)

The AAR valve hose plugs into the air cleaner.
I'll bet you have a leaky worn out Throttle body. Check out how tight the shaft to body play is, as it should be nice and tight with smooth action. The fix is to have bronze bushings put into it which make for a smooth throttle.

The engine is getting air from somewhere....tb,injector seals, bad hoses etc.

Thanks Geoff, I suspected the throttle body due to its frozen position when I first tried opening it. I literally had to soak it in PB Blaster and scrape the white oxidation from the inside of the barrel to get it to move. After taking it apart and cleaning it it still felt like the brass plate was getting stuck within. Caused for a had throttle peddal with no smoothness of giving it the gas. It's better now because I took it apart again and used a small wire brush wheel on my dremmel to knock off other deposits. The shaft does feel a wee bit wobbley. I have 2 1.7 throttle bodies. I wonder... maybe the bushings will fit from them???? (IMG:style_emoticons/default/idea.gif)

UPDATE!!!

I re-timed it and it was just a BCH off. It slowed the idle to about 1050 with the idle screw closed. The AAR isn't closing completely. It's staying opn a BCH also but when I plug it off there's no change in idle speed. I think Geoff is on to something about the throttle body leaking. There could be a few other areas with minuscuel leak probs. The good thing is... it's running great and I don't wanna sell it no more (IMG:style_emoticons/default/boldblue.gif)

I had the same problem on my 76 2.0 and found the intake manifold bolts were loose?!!
I also had the decel valve go bad on another instance.

no, there are no bushings in any of the stock Throttle bodies. I had a automachine shop install them in mine as they had some in stock that would work. Wow, what a difference!

The other thing is to check the advance/retard plate in the dizzy to see if its sticking.
How steady is the timing mark when you shine the lite on it??? If its wobbly by over a 1/2" then the dizzy shaft is wearing out too. Gives you all sorts of problems with acurate timing (ignition and tigger points).

Ya, the timing mark is wobbly. Looks just like my 1.7 did before I installed the Pertronics. I have the Pertonics in this one but it doesn't make a difference. Ani't it something what a slight movement of the dizzy can accomplish (IMG:style_emoticons/default/rolleyes.gif) If I had a 3rd hand to hold the engine speed at 3500 rpms it'd make life alot simpler whilst timing (IMG:style_emoticons/default/cool.gif)

Geoff, did the bushings make for a smooth feel of the gas peddal with no sticking when you first apply pressure to it?

Bruce, the wear in there shouldn't translate very much to the pedal... when they are worn, you may notice a clicking but it's nearly nothing, I noticed on one I sold a couple years ago that it clicked lightly, if I floored it.

How's your pedal cluster? May a cable be doing something nasty in, or out of a tube?
