I was looking at the pelican one, it is good but not for my 76. I have a hose that is not connected under the airbox bottom, goes to the solenoid on the driver side plenum towards the rear...i did not see this part in the diagram as it has more connections than in the pelican diagram(the show it ending at the manifold and mine goes on)

Nick,

The hose to the rear of the plenum (driver's side) is the inlet from the Aux. Air Regulator - its combined with the Cold Start Injector (maybe what you called a solenoid). The hose goes from there to the AAR (which sits forward of the plenum). Then the inlet for the AAR goes up to the Air box (above the throttle body).

I know I have a couple of diagrams. If you can get me a FAX number I could get them to you tomorrow.

Enjoy!

There is also the small hose off the vacumm advance that is just stuffed under the plenum as the port is blocked on the 74 and later TB's.
Never seen any solnoids under the plenum, so maybe thats the AAR valve???

Then I'll bet its not a 76 TB. Does it have the big spring on the lever?

I think we may need some pics to be able to figure that out. Could it be an EGR dashpot? Can you point us to a picture in the Haynes manual that shows the part?

That is the cold start valve. The big hose goes to vacuum, the small one is a fuel line.

the hose is like fuel line so that makes sense. I need to look at the fuel schematics closer. I will take some pictures tonight(if it isn't raining )

The fuel line attaches to the "T" on the drivrers side fuel rail. I have mine blocked off to accomadate a fuel pressure gauge, but ya might want to keep it in your climate.

If you are talking about this, it is the cold start valve. The hose you see is a fuel line. Under it, out of view is a larger (1/2 inch) fitting that goes to the aux air valve.

AAR? Only thing I can think of with two hoses and one wire. That should be at the front of the plenum on the drivers side.

Top port goes to air cleaner, bottom port goes to the cold start valve. It plugs into a wire that is included the coil /diz harness.

i will take some pictures, mine is very different. i have a good 1/2" hose venting the oil filler to the airbox, and the arrangement of the components is different. the reall funny thing is the car had a slight pop and miss off idel. I tried to adjust/clean the throttle switch and it still did it, so i got a new one, still did it. then I started thinking, it seemed like a lean miss like when a carb's accel pump is bad, so I adjusted the mixture and found that the mixture was cranked all the way clockwise. the car started to run better as I turned it ccw. the more i turned it the more i needed to turn the idle screw out. the po had the idle screw all the way in. now it takes throttle and reves right up like it should...the big thing is all the manuals and such leave out the 75/76 cars...i have an air pump and all that crap...no egr all the stuff i see is 73/74
