Greetings again from Utah!

Further work and diagnosis on the EVER SO FUSSY  92 S4 yields new information - THANKS to everyone who suggested things earlier!

Pulled the fuel rail and checked for spritzes while cranking, it does.  Have NOT done a pressure test on the system yet

Removed all rubber tubes for the intake system, cleaned the oily goop from inside them, also cleaned several oily and dusty boogers off the inside of the MAF, till its shiny and clean, reassembled the plumbing, no discernable leaks.

Spun the turbo shaft by hand, cannot detect any binding, however there is slight radial play when one wiggles the shaft side to side and up and down.. I dont know whats in tolerance, but it spins freely, even when cranking the engine in a no start situation.

NOW the car does this:  Starts and runs fine, for a minute or two, then begins a mild miss, which progressivly gets worse, until the car is just idling chunk chunk chunk chunk chunk, and finally dies.  It appears that high revving the engine, makes it happen sooner, however since it takes several hours chilling out, for me to repeat this, that data is sketchy...

Any thoughts from the hive would be lovely!!

Fuel filter(s) ?  
Cat Meltdown?
Heat...?

Thanks in advance
Ken
