[T3] FI trouble

[Cody Andresen <cody@codyandresen.com>]

<x-flowed>My 1970 Fastback has quickly developed a chronic problem with the FI. 
The car was difficult getting started so I decided to take it into my 
local mechanic.  He was unable to figure it out.

Up until recently, the car would start but would sound like it was 
"sputtering" under load or at high RPMs.  The mechanic replaced the 
vacuum advance with a used one that he claimed was working.  The 
plugs were replaced, valves were adjusted and the timing was perfect.

When the car last started (it's dead now), the engine would stall if 
the car came under to0 heavy of a load  (ie. I would give the engine 
too much gas).  I was driving in the city, no hills, to avoid a 
stall.  When the car did stall, I had a heck of a time getting it 
started and had to play with the accelerator, got it started when I 
had it fully depressed.

The mechanic I took it to for a second opinion wants to do a carb 
conversion.  I'm not convinced this is the best alternative.  I've 
taken matters into my own hands and have been reading up in my 
Bently.  I'm also armed with my volt meter from Radio Shack.

For a newbie who wants to do some diagnostics on this type of FI, is 
there a good method of deduction that I should follow (besides what 
I've read in the Bently manual)?  I just want to avoid stupid 
mistakes and not fry any of the electronics.
