Thanks, to everyone...I will do exactly as suggested. This car sat for 
several months, and after air, fuel filter, plugs and MAF sensor 
cleaning there is already a world of difference in how she runs, 02 
sensor testing or replacement and EGR, intake cleaning also in line to 
be done. If at some point if I have to ditch the engine most of what I 
will have done will be of benefit anyway (I'll eat the gasket costs and 
my time for the intake job). Vacuum  lines appear good. The engine is 
dry as a bone, all fluids look very clean.
The car runs great other than some hesitation and occasional black 
smoke. Only code I get is for EGR.
Unfortunately, t-belt needs to be done and  t-stat is busted open, which 
won't help the rich running either.
Having given up my 94 S-4 I finally found a big Audi I can actually work 
on. But I do miss the power...these V6's are slow as molasses.
Still haven't come across a step by step strut insert replacement write 
up...one for idiots, which is what I need next.
Thanks again.
95 A6 5 speed 135k miles and new.
91 200 TQ 160k miles and costing me a fortune.
87 4KQ cheap and reliable but getting hard to shift in 1'st and reverse, 
new clutch recently. Does this have to be internal gearbox wear?
