Fired her up after the following work:
New thermostat
ported base
SLP runners
ported plenum
rebuilt distributor
new cap and rotor
Accel coil
aftermarket chrome steel valve covers
adjustable fuel pressure regulator
FIC Bosch III injectors
New EGR valve
Runs like a scared rabbit! BUT AT FULL THROTTLE!!!!! It will not idle down. The throttle body is completely closed, it is NOT wide open.
I was extremely careful to mark all the sensors, hoses, wires etc. No parts left over and all wires connected back to where they were originally. Although I had the throttle body off I did not mess with the Idle control motor as I had cleaned that about a month before and it idled normally then. My tach is way off so it is pegged out anyway and I am unable to tell what the rpm is.
The only thing that remotely comes to mind is that when I finished putting the intake together I realized that I had not run the TV cable inside the driver's side runners. I did that after the fact by loosening that runner. I had to push very hard on the TV cable "housing" and even tapped it with a hammer and large metal bar in order to get it to squeeze through the opening between the front SLP runner and the fuel rail. The squarish housing that sits just behind the bracket for the TV cable is a bit scuffed but not deformed or anything.
Any ideas?
I am really happy with how strong it sounds at full throttle though - hell that says something about those Bosch IIIs anyway.

 

I had the exact same problem, after fitting SLP runners. Make sure you didn't do what I did, and install the runners on the wrong sides. Make sure the runner with the slight taper on the top where it angles down towards the throttle body, is flush with the plenum! If there on wrong you'll have a massive vacuum leak, and a racing high idle.

 

I bought these used so that is probably what I did. They were not marked (that I could tell).
Thank you - and oh the agony of taking it all apart and starting over. :o
Here are pics - can you tell if I have them on the wrong side?

 

Yep. Your on backwards. Don't worry its not that bad.....You can reuse your gaskets if your careful. Besides now you'll be a pro!!
