Fuel injector Rehab, cont'd

[TooManyAudis at aol.com]

Couple of other points -- brand new plugs -- in fact, did a timing belt 
change, along with plugs, cap, rotor, fuel filter and seemingly hundreds of other 
miscellaneous parts as soon as I got the car -- about 1,000 miles ago or less.

Also, I spoke to an owner of a foreign car service center (ran into him at 
the VW dealership while picking up replacement wires for a couple I managed to 
short out) and he suggested the the problem sounded more like a fuel pressure 
problem, with the most likely culprit being the check valve.  Any thoughts?

I'm looking to resolve a persistant warm start problem with my 91 200q.
Cold
starts and hot starts are fine, but a "warm start" -- 15 min to 2 hrs after
running -- produces a very hard start condition, where I usually have to
cycle
through 3 or 4 attempts at starting before success.

Indications most likely point to leaky fuel injectors, and was considering
cleaning them (www.injector.com, unless a better source is warranted) or
replacing them if I can find injectors for significantly less than the $150
or so
through the various worldpac suppliers.

Has anyone had success with cleaning, or found a much more reasonable source
for replacement injectors?  Alternately, should I be looking elsewhere to
resolve the hard warm start issue?

I figure at 217k miles, the injectors have earned a rehab at the very least.

Thanks,

-- Tom
