Stopped Knocking Noise ... But ... Now In TROUBLE !!

My Wife's Cougar ('86 XR-7 Turbo) was making a Low-Frequency Rattle.  She asked around, up here, and found out that a Water Pump was the most-likely cause.
(She is, still, having trouble with the HVAC (No Heat) and I thought I would replace the Thermostat, with a Hotter One, while I was Replacing the Water Pump.)

I got both items replaced and went to check for Coolant Leaks. 
... something 'odd' seems to have happened when I tried to crank the engine ...

The Engine was running like a sewing machine when she parked it on Friday Afternoon, and I started this process on Saturday Morning.
After letting all of the RTV Set/Cure  - I went outside, this morning, to tighten and check everything.

When I turn the engine over it will start... run and will Idle Up.
But it feels like it has a 'Miss-Fire' and, when Idled Down ... the engine stalls and quits.

-- any ideas ? --

Did you bump the air intake tube off? I know I had symptoms similar on my XR-7 and the tube between the MAF and the intake was off just enough to suck air.

I think he may have meant the VAM meter, had the same problem and the tube from VAM to turbo inlet was off just enough at bottom that it caused it to stall out..
