I'm a big fan of Seafoam, but here it might confuse symptoms.

As for how you spot an injector with a bit of crud holding it open, unless you pull them and inspect them [where an error code could hopefully narrow it down], one of the symptoms is overly rich running--as in really really rich to the point where you smell fuel.

There are pro injector cleaners, where if you have to ask how to use them, you should probably pay someone.

I will look for frayed or damaged wires. I didn't see any when I was testing the ohmage but that means nothing. Thank you so far for the responses. This vehicle was supposed to be the safe, reliable, family car, bought from the family friend who "took care of it". We've put a few grand in cash into it already in just two years.
You could swap that injector with another position and see if the error code moves.
If it does, suggest start with that injector.

Plugs being black... darkish gray maybe but not black. If all of them are the same color, possibly something is keeping your engine enriched, but you'd want a "plug whisperer" to take a look at them.

The injector error you are seeing is probably the best item to follow, either with a new injector or by swapping positions.

Re: Shuttering, stalling, rough idle.

You could look for a junk yard PCM. It only needs to be programmed by the stealer or someone with a DRBIII scanner.

Re: Shuttering, stalling, rough idle.

Mechanic says it's a bunch of things. A few cylinders have no compression. Timing is off. Some of the cylinders are flooded with fuel. Computer is fine but it is overwhelmingly mechanical in nature. He said it wouldn't even be worth fixing because I would need a new engine. Considering that we picked it up for $4000.00 2 years ago and have put at least that much into it since, I think I will let it die. It is beyond frustrating.
Thank you to everyone who offered help and advice.

Re: Shuttering, stalling, rough idle.

No compression in some of the cylinders does me think about two possililities: or a rocker arm fell off at the respective cylinders, or the small dowel which orients the timing chain sprocket to the cam shaft, sheared of. This will mess up the timing, cause no compression at the cylinders of that bank, but also will damage the exhaust valves which are open, since its an interference engine.
