God-danged commies! That's probably what's doing it!

Seriously though, did you try googling for cadillac injector or cadillac injector repair, cadillac injector flooding, etc? You might turn up some ideas that way.

Hit a parts store like NAPA or Shucks and get three bottles of injector cleaner to put in the gas tank. That might clean things up. If not, it's quite likely there's a piece of crud jamming the injector open. Some injectors in throttle body systems can be carefully taken apart enough to clean/replace the inlet screen and get junk out of the needle and orifice.

Rebuilt injectors are $$$. It's still possible to find Cimarron parts used, I had to replace the digital instrument panel in my 1986 V6 and find an engine computer. The car sat in a junkyard for two years and all they ever sold off it was the computer and left rear window motor. :) It had been clipped lightly across the nose so I had to replace the front bumper, fenders, hood, fiberglass nosepiece, etc. No structural damage. Sure has made for a nice driving little car. :)

FYI: up through 1986, the GM engine computers are all identical. The difference is in the two plugin chips under the cover. As long as those chips are good, you can swap them into any GM computer from the same era, 4, 6 or 8 cylinder. Just don't insert them backwards! GM changed the computer design in 1987 but it's the same deal, just the two chips, except they're on a common carrier that's keyed to make it impossible to install backwards.

The small chip is called the "calpack". It contains the basic program to make the engine run. The other chip contains engine specific data plus a RAM area that stores self-programmed calibration data. This RAM gets erased when you disconnect the battery, which is why the car will run rough for a bit when first started after reconnecting the battery. If the car runs like crap ALL the time, this chip may be fried.
