While taking a look at my local Mazda dealership, the red car wouldn't start -- I had to tow it to the repair shop across the street and the diagnosis was 1 bad fuel injector.
The labor was quoted at 4 hours, but the bulk of the cost was from original Porsche Factory Fuel Injectors:
Instead I tried Pelican Parts for some rebuilt injectors from GB Re-manufacturing -- we'll see how they do tomorrow. [4 rebuild injectors = $200+ with seal kits sold separately]
It also looks like this is a popular item to list on eBay:

Concern with New Injectors:
-> For a car this old [going on 30 years] the stock parts may have been sitting in storage/inventory and degraded
Concern with Used Injectors:
-> Shorter lifespan and if re-manufactured, possibility of missing original equipment spec.
[Updated Jan. 2015]
Final Verdict:
I've been running the rebuilt injectors for over a year now and no problems!
